Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121814, here are decompositions:

  • 103 + 121711 = 121814
  • 127 + 121687 = 121814
  • 181 + 121633 = 121814
  • 193 + 121621 = 121814
  • 223 + 121591 = 121814
  • 283 + 121531 = 121814
  • 307 + 121507 = 121814
  • 313 + 121501 = 121814

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 121,814 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 121814 first appears in π at position 319,447 of the decimal expansion (the 319,447ordinal-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.
