Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581700, here are decompositions:

  • 13 + 581687 = 581700
  • 17 + 581683 = 581700
  • 37 + 581663 = 581700
  • 43 + 581657 = 581700
  • 61 + 581639 = 581700
  • 83 + 581617 = 581700
  • 101 + 581599 = 581700
  • 103 + 581597 = 581700

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 581,700 and was likely granted around 1896.

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

Position in π

The digit sequence 581700 first appears in π at position 226,866 of the decimal expansion (the 226,866ordinal-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.
