Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121694, here are decompositions:

  • 7 + 121687 = 121694
  • 61 + 121633 = 121694
  • 73 + 121621 = 121694
  • 103 + 121591 = 121694
  • 163 + 121531 = 121694
  • 193 + 121501 = 121694
  • 241 + 121453 = 121694
  • 337 + 121357 = 121694

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 121,694 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 121694 first appears in π at position 268,802 of the decimal expansion (the 268,802ordinal-suffix:nd 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.
