Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518086, here are decompositions:

  • 3 + 518083 = 518086
  • 29 + 518057 = 518086
  • 137 + 517949 = 518086
  • 167 + 517919 = 518086
  • 263 + 517823 = 518086
  • 269 + 517817 = 518086
  • 347 + 517739 = 518086
  • 353 + 517733 = 518086

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 518,086 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 518086 first appears in π at position 638,838 of the decimal expansion (the 638,838ordinal-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.
