Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161914, here are decompositions:

  • 3 + 161911 = 161914
  • 41 + 161873 = 161914
  • 83 + 161831 = 161914
  • 107 + 161807 = 161914
  • 131 + 161783 = 161914
  • 173 + 161741 = 161914
  • 197 + 161717 = 161914
  • 353 + 161561 = 161914

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 161,914 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 161914 first appears in π at position 970,514 of the decimal expansion (the 970,514ordinal-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.
