Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168916, here are decompositions:

  • 3 + 168913 = 168916
  • 17 + 168899 = 168916
  • 23 + 168893 = 168916
  • 29 + 168887 = 168916
  • 47 + 168869 = 168916
  • 53 + 168863 = 168916
  • 113 + 168803 = 168916
  • 173 + 168743 = 168916

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 168,916 and was likely granted around 1874.

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

Position in π

The digit sequence 168916 first appears in π at position 769,872 of the decimal expansion (the 769,872ordinal-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.
