Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121746, here are decompositions:

  • 19 + 121727 = 121746
  • 59 + 121687 = 121746
  • 109 + 121637 = 121746
  • 113 + 121633 = 121746
  • 137 + 121609 = 121746
  • 139 + 121607 = 121746
  • 167 + 121579 = 121746
  • 193 + 121553 = 121746

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 121,746 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 121746 first appears in π at position 294,438 of the decimal expansion (the 294,438ordinal-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.
