Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126992, here are decompositions:

  • 3 + 126989 = 126992
  • 31 + 126961 = 126992
  • 43 + 126949 = 126992
  • 79 + 126913 = 126992
  • 211 + 126781 = 126992
  • 241 + 126751 = 126992
  • 379 + 126613 = 126992
  • 409 + 126583 = 126992

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 126,992 and was likely granted around 1872.

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

Position in π

The digit sequence 126992 first appears in π at position 161,433 of the decimal expansion (the 161,433ordinal-suffix:rd 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.
