Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126650, here are decompositions:

  • 19 + 126631 = 126650
  • 37 + 126613 = 126650
  • 67 + 126583 = 126650
  • 103 + 126547 = 126650
  • 109 + 126541 = 126650
  • 151 + 126499 = 126650
  • 157 + 126493 = 126650
  • 163 + 126487 = 126650

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 126,650 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 126650 first appears in π at position 357,955 of the decimal expansion (the 357,955ordinal-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.
