Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126386, here are decompositions:

  • 37 + 126349 = 126386
  • 79 + 126307 = 126386
  • 157 + 126229 = 126386
  • 163 + 126223 = 126386
  • 307 + 126079 = 126386
  • 349 + 126037 = 126386
  • 367 + 126019 = 126386
  • 373 + 126013 = 126386

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 126,386 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 126386 first appears in π at position 394,878 of the decimal expansion (the 394,878ordinal-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.
