Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166122, here are decompositions:

  • 23 + 166099 = 166122
  • 41 + 166081 = 166122
  • 59 + 166063 = 166122
  • 79 + 166043 = 166122
  • 101 + 166021 = 166122
  • 109 + 166013 = 166122
  • 139 + 165983 = 166122
  • 181 + 165941 = 166122

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 166,122 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 166122 first appears in π at position 74,234 of the decimal expansion (the 74,234ordinal-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.
