Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127124, here are decompositions:

  • 43 + 127081 = 127124
  • 73 + 127051 = 127124
  • 157 + 126967 = 127124
  • 163 + 126961 = 127124
  • 181 + 126943 = 127124
  • 211 + 126913 = 127124
  • 367 + 126757 = 127124
  • 373 + 126751 = 127124

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 127,124 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 127124 first appears in π at position 206,675 of the decimal expansion (the 206,675ordinal-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.
