Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761240, here are decompositions:

  • 3 + 8761237 = 8761240
  • 71 + 8761169 = 8761240
  • 83 + 8761157 = 8761240
  • 101 + 8761139 = 8761240
  • 107 + 8761133 = 8761240
  • 233 + 8761007 = 8761240
  • 263 + 8760977 = 8761240
  • 281 + 8760959 = 8761240

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 8,761,240 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 8761240 first appears in π at position 22,028 of the decimal expansion (the 22,028ordinal-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.
