Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123118, here are decompositions:

  • 5 + 123113 = 123118
  • 41 + 123077 = 123118
  • 59 + 123059 = 123118
  • 101 + 123017 = 123118
  • 179 + 122939 = 123118
  • 197 + 122921 = 123118
  • 227 + 122891 = 123118
  • 251 + 122867 = 123118

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 123,118 and was likely granted around 1871.

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

Position in π

The digit sequence 123118 first appears in π at position 377,780 of the decimal expansion (the 377,780ordinal-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.
