Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751938, here are decompositions:

  • 7 + 8751931 = 8751938
  • 31 + 8751907 = 8751938
  • 67 + 8751871 = 8751938
  • 79 + 8751859 = 8751938
  • 109 + 8751829 = 8751938
  • 157 + 8751781 = 8751938
  • 199 + 8751739 = 8751938
  • 211 + 8751727 = 8751938

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 8,751,938 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 8751938 first appears in π at position 978,573 of the decimal expansion (the 978,573ordinal-suffix:rd 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.
