Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737880, here are decompositions:

  • 7 + 8737873 = 8737880
  • 13 + 8737867 = 8737880
  • 31 + 8737849 = 8737880
  • 37 + 8737843 = 8737880
  • 79 + 8737801 = 8737880
  • 97 + 8737783 = 8737880
  • 139 + 8737741 = 8737880
  • 163 + 8737717 = 8737880

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 8,737,880 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 8737880 first appears in π at position 324,825 of the decimal expansion (the 324,825ordinal-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.
