Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743072, here are decompositions:

  • 5 + 8743067 = 8743072
  • 29 + 8743043 = 8743072
  • 53 + 8743019 = 8743072
  • 71 + 8743001 = 8743072
  • 131 + 8742941 = 8743072
  • 251 + 8742821 = 8743072
  • 293 + 8742779 = 8743072
  • 383 + 8742689 = 8743072

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 8,743,072 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 8743072 first appears in π at position 64,157 of the decimal expansion (the 64,157ordinal-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.
