Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517888, here are decompositions:

  • 11 + 517877 = 517888
  • 71 + 517817 = 517888
  • 149 + 517739 = 517888
  • 167 + 517721 = 517888
  • 251 + 517637 = 517888
  • 269 + 517619 = 517888
  • 311 + 517577 = 517888
  • 317 + 517571 = 517888

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 517,888 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 517888 first appears in π at position 700,829 of the decimal expansion (the 700,829ordinal-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.
