Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748140, here are decompositions:

  • 3 + 8748137 = 8748140
  • 31 + 8748109 = 8748140
  • 43 + 8748097 = 8748140
  • 97 + 8748043 = 8748140
  • 109 + 8748031 = 8748140
  • 139 + 8748001 = 8748140
  • 199 + 8747941 = 8748140
  • 211 + 8747929 = 8748140

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 8,748,140 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 8748140 first appears in π at position 923,469 of the decimal expansion (the 923,469ordinal-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.
