Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501940, here are decompositions:

  • 29 + 501911 = 501940
  • 113 + 501827 = 501940
  • 137 + 501803 = 501940
  • 233 + 501707 = 501940
  • 239 + 501701 = 501940
  • 281 + 501659 = 501940
  • 317 + 501623 = 501940
  • 347 + 501593 = 501940

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 501,940 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 501940 first appears in π at position 230,237 of the decimal expansion (the 230,237ordinal-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.
