Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491036, here are decompositions:

  • 43 + 490993 = 491036
  • 67 + 490969 = 491036
  • 79 + 490957 = 491036
  • 109 + 490927 = 491036
  • 199 + 490837 = 491036
  • 373 + 490663 = 491036
  • 409 + 490627 = 491036
  • 457 + 490579 = 491036

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 491,036 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 491036 first appears in π at position 393,843 of the decimal expansion (the 393,843ordinal-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.
