Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500440, here are decompositions:

  • 23 + 500417 = 500440
  • 47 + 500393 = 500440
  • 71 + 500369 = 500440
  • 107 + 500333 = 500440
  • 191 + 500249 = 500440
  • 263 + 500177 = 500440
  • 383 + 500057 = 500440
  • 431 + 500009 = 500440

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 500,440 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 500440 first appears in π at position 623,116 of the decimal expansion (the 623,116ordinal-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.
