Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513288, here are decompositions:

  • 5 + 513283 = 513288
  • 11 + 513277 = 513288
  • 19 + 513269 = 513288
  • 31 + 513257 = 513288
  • 131 + 513157 = 513288
  • 151 + 513137 = 513288
  • 157 + 513131 = 513288
  • 179 + 513109 = 513288

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 513,288 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 513288 first appears in π at position 568,701 of the decimal expansion (the 568,701ordinal-suffix:st 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.
