Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500640, here are decompositions:

  • 11 + 500629 = 500640
  • 37 + 500603 = 500640
  • 53 + 500587 = 500640
  • 61 + 500579 = 500640
  • 73 + 500567 = 500640
  • 113 + 500527 = 500640
  • 131 + 500509 = 500640
  • 139 + 500501 = 500640

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 500,640 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 500640 first appears in π at position 99,565 of the decimal expansion (the 99,565ordinal-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.
