Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740008, here are decompositions:

  • 5 + 8740003 = 8740008
  • 41 + 8739967 = 8740008
  • 47 + 8739961 = 8740008
  • 71 + 8739937 = 8740008
  • 89 + 8739919 = 8740008
  • 97 + 8739911 = 8740008
  • 107 + 8739901 = 8740008
  • 131 + 8739877 = 8740008

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 8,740,008 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 8740008 first appears in π at position 355,765 of the decimal expansion (the 355,765ordinal-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.
