Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137570, here are decompositions:

  • 3 + 137567 = 137570
  • 79 + 137491 = 137570
  • 127 + 137443 = 137570
  • 157 + 137413 = 137570
  • 211 + 137359 = 137570
  • 229 + 137341 = 137570
  • 331 + 137239 = 137570
  • 373 + 137197 = 137570

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 137,570 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 137570 first appears in π at position 10,308 of the decimal expansion (the 10,308ordinal-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.
