Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126930, here are decompositions:

  • 7 + 126923 = 126930
  • 17 + 126913 = 126930
  • 71 + 126859 = 126930
  • 73 + 126857 = 126930
  • 79 + 126851 = 126930
  • 103 + 126827 = 126930
  • 107 + 126823 = 126930
  • 149 + 126781 = 126930

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 126,930 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 126930 first appears in π at position 33,927 of the decimal expansion (the 33,927ordinal-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.
