Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499900, here are decompositions:

  • 3 + 499897 = 499900
  • 17 + 499883 = 499900
  • 47 + 499853 = 499900
  • 113 + 499787 = 499900
  • 227 + 499673 = 499900
  • 239 + 499661 = 499900
  • 251 + 499649 = 499900
  • 263 + 499637 = 499900

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 499,900 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 499900 first appears in π at position 139,349 of the decimal expansion (the 139,349ordinal-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.
