Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499878, here are decompositions:

  • 59 + 499819 = 499878
  • 97 + 499781 = 499878
  • 131 + 499747 = 499878
  • 139 + 499739 = 499878
  • 149 + 499729 = 499878
  • 167 + 499711 = 499878
  • 191 + 499687 = 499878
  • 199 + 499679 = 499878

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 499,878 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 499878 first appears in π at position 572,148 of the decimal expansion (the 572,148ordinal-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.
