Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163164, here are decompositions:

  • 13 + 163151 = 163164
  • 17 + 163147 = 163164
  • 37 + 163127 = 163164
  • 47 + 163117 = 163164
  • 101 + 163063 = 163164
  • 103 + 163061 = 163164
  • 137 + 163027 = 163164
  • 167 + 162997 = 163164

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 163,164 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 163164 first appears in π at position 115,587 of the decimal expansion (the 115,587ordinal-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.
