Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121994, here are decompositions:

  • 31 + 121963 = 121994
  • 43 + 121951 = 121994
  • 73 + 121921 = 121994
  • 127 + 121867 = 121994
  • 151 + 121843 = 121994
  • 283 + 121711 = 121994
  • 307 + 121687 = 121994
  • 373 + 121621 = 121994

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 121,994 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 121994 first appears in π at position 359,907 of the decimal expansion (the 359,907ordinal-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.
