Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515008, here are decompositions:

  • 41 + 514967 = 515008
  • 59 + 514949 = 515008
  • 149 + 514859 = 515008
  • 167 + 514841 = 515008
  • 239 + 514769 = 515008
  • 251 + 514757 = 515008
  • 257 + 514751 = 515008
  • 269 + 514739 = 515008

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 515,008 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 515008 first appears in π at position 236,182 of the decimal expansion (the 236,182ordinal-suffix:nd 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.
