Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499220, here are decompositions:

  • 31 + 499189 = 499220
  • 37 + 499183 = 499220
  • 61 + 499159 = 499220
  • 79 + 499141 = 499220
  • 103 + 499117 = 499220
  • 157 + 499063 = 499220
  • 181 + 499039 = 499220
  • 193 + 499027 = 499220

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 499,220 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 499220 first appears in π at position 828,294 of the decimal expansion (the 828,294ordinal-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.
