Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665740, here are decompositions:

  • 23 + 8665717 = 8665740
  • 37 + 8665703 = 8665740
  • 73 + 8665667 = 8665740
  • 89 + 8665651 = 8665740
  • 107 + 8665633 = 8665740
  • 137 + 8665603 = 8665740
  • 157 + 8665583 = 8665740
  • 173 + 8665567 = 8665740

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 8,665,740 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 8665740 first appears in π at position 427,073 of the decimal expansion (the 427,073ordinal-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.
