Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162122, here are decompositions:

  • 3 + 162119 = 162122
  • 13 + 162109 = 162122
  • 31 + 162091 = 162122
  • 43 + 162079 = 162122
  • 139 + 161983 = 162122
  • 151 + 161971 = 162122
  • 199 + 161923 = 162122
  • 211 + 161911 = 162122

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 162,122 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 162122 first appears in π at position 935,727 of the decimal expansion (the 935,727ordinal-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.
