Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501690, here are decompositions:

  • 31 + 501659 = 501690
  • 53 + 501637 = 501690
  • 67 + 501623 = 501690
  • 73 + 501617 = 501690
  • 89 + 501601 = 501690
  • 97 + 501593 = 501690
  • 113 + 501577 = 501690
  • 127 + 501563 = 501690

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 501,690 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 501690 first appears in π at position 373,546 of the decimal expansion (the 373,546ordinal-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.
