Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506640, here are decompositions:

  • 11 + 506629 = 506640
  • 31 + 506609 = 506640
  • 41 + 506599 = 506640
  • 47 + 506593 = 506640
  • 67 + 506573 = 506640
  • 89 + 506551 = 506640
  • 103 + 506537 = 506640
  • 107 + 506533 = 506640

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 506,640 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 506640 first appears in π at position 873,352 of the decimal expansion (the 873,352ordinal-suffix:nd 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.
