Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126844, here are decompositions:

  • 5 + 126839 = 126844
  • 17 + 126827 = 126844
  • 83 + 126761 = 126844
  • 101 + 126743 = 126844
  • 131 + 126713 = 126844
  • 191 + 126653 = 126844
  • 233 + 126611 = 126844
  • 293 + 126551 = 126844

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 126,844 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 126844 first appears in π at position 913,738 of the decimal expansion (the 913,738ordinal-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.
