Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499986, here are decompositions:

  • 7 + 499979 = 499986
  • 13 + 499973 = 499986
  • 17 + 499969 = 499986
  • 29 + 499957 = 499986
  • 43 + 499943 = 499986
  • 59 + 499927 = 499986
  • 83 + 499903 = 499986
  • 89 + 499897 = 499986

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 499,986 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 499986 first appears in π at position 292,119 of the decimal expansion (the 292,119ordinal-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.
