Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740816, here are decompositions:

  • 17 + 8740799 = 8740816
  • 23 + 8740793 = 8740816
  • 53 + 8740763 = 8740816
  • 59 + 8740757 = 8740816
  • 89 + 8740727 = 8740816
  • 137 + 8740679 = 8740816
  • 167 + 8740649 = 8740816
  • 173 + 8740643 = 8740816

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 8,740,816 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 8740816 first appears in π at position 823,322 of the decimal expansion (the 823,322ordinal-suffix:nd 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.
