Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123992, here are decompositions:

  • 3 + 123989 = 123992
  • 13 + 123979 = 123992
  • 19 + 123973 = 123992
  • 61 + 123931 = 123992
  • 139 + 123853 = 123992
  • 163 + 123829 = 123992
  • 331 + 123661 = 123992
  • 373 + 123619 = 123992

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 123,992 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 123992 first appears in π at position 872,754 of the decimal expansion (the 872,754ordinal-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.
