Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126700, here are decompositions:

  • 17 + 126683 = 126700
  • 47 + 126653 = 126700
  • 59 + 126641 = 126700
  • 89 + 126611 = 126700
  • 149 + 126551 = 126700
  • 227 + 126473 = 126700
  • 239 + 126461 = 126700
  • 257 + 126443 = 126700

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 126,700 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 126700 first appears in π at position 220,064 of the decimal expansion (the 220,064ordinal-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.
