Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747186, here are decompositions:

  • 67 + 8747119 = 8747186
  • 103 + 8747083 = 8747186
  • 223 + 8746963 = 8747186
  • 229 + 8746957 = 8747186
  • 307 + 8746879 = 8747186
  • 313 + 8746873 = 8747186
  • 337 + 8746849 = 8747186
  • 367 + 8746819 = 8747186

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,747,186 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8747186 first appears in π at position 262,137 of the decimal expansion (the 262,137ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
