Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108816, here are decompositions:

  • 13 + 108803 = 108816
  • 17 + 108799 = 108816
  • 23 + 108793 = 108816
  • 47 + 108769 = 108816
  • 89 + 108727 = 108816
  • 107 + 108709 = 108816
  • 109 + 108707 = 108816
  • 139 + 108677 = 108816

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 108,816 and was likely granted around 1871.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 108816 first appears in π at position 733,152 of the decimal expansion (the 733,152ordinal-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.
