Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126662, here are decompositions:

  • 31 + 126631 = 126662
  • 61 + 126601 = 126662
  • 79 + 126583 = 126662
  • 163 + 126499 = 126662
  • 181 + 126481 = 126662
  • 229 + 126433 = 126662
  • 241 + 126421 = 126662
  • 313 + 126349 = 126662

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 126,662 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 126662 first appears in π at position 426,256 of the decimal expansion (the 426,256ordinal-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.
