Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518736, here are decompositions:

  • 7 + 518729 = 518736
  • 19 + 518717 = 518736
  • 37 + 518699 = 518736
  • 47 + 518689 = 518736
  • 79 + 518657 = 518736
  • 139 + 518597 = 518736
  • 149 + 518587 = 518736
  • 157 + 518579 = 518736

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 518,736 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 518736 first appears in π at position 176,115 of the decimal expansion (the 176,115ordinal-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.
