Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561736, here are decompositions:

  • 3 + 561733 = 561736
  • 23 + 561713 = 561736
  • 137 + 561599 = 561736
  • 317 + 561419 = 561736
  • 347 + 561389 = 561736
  • 359 + 561377 = 561736
  • 389 + 561347 = 561736
  • 563 + 561173 = 561736

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 561,736 and was likely granted around 1895.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 561736 first appears in π at position 455,537 of the decimal expansion (the 455,537ordinal-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.
