Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500646, here are decompositions:

  • 17 + 500629 = 500646
  • 43 + 500603 = 500646
  • 59 + 500587 = 500646
  • 67 + 500579 = 500646
  • 79 + 500567 = 500646
  • 127 + 500519 = 500646
  • 137 + 500509 = 500646
  • 163 + 500483 = 500646

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 500,646 and was likely granted around 1893.

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

Position in π

The digit sequence 500646 first appears in π at position 485,545 of the decimal expansion (the 485,545ordinal-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.
