Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126854, here are decompositions:

  • 3 + 126851 = 126854
  • 31 + 126823 = 126854
  • 73 + 126781 = 126854
  • 97 + 126757 = 126854
  • 103 + 126751 = 126854
  • 151 + 126703 = 126854
  • 163 + 126691 = 126854
  • 223 + 126631 = 126854

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 126,854 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 126854 first appears in π at position 688,708 of the decimal expansion (the 688,708ordinal-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.
