Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126988, here are decompositions:

  • 131 + 126857 = 126988
  • 137 + 126851 = 126988
  • 149 + 126839 = 126988
  • 227 + 126761 = 126988
  • 269 + 126719 = 126988
  • 347 + 126641 = 126988
  • 647 + 126341 = 126988
  • 677 + 126311 = 126988

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 126,988 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 126988 first appears in π at position 781,884 of the decimal expansion (the 781,884ordinal-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.
