Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501938, here are decompositions:

  • 7 + 501931 = 501938
  • 97 + 501841 = 501938
  • 109 + 501829 = 501938
  • 337 + 501601 = 501938
  • 487 + 501451 = 501938
  • 571 + 501367 = 501938
  • 709 + 501229 = 501938
  • 751 + 501187 = 501938

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 501,938 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 501938 first appears in π at position 571,433 of the decimal expansion (the 571,433ordinal-suffix:rd 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.
