Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518712, here are decompositions:

  • 13 + 518699 = 518712
  • 23 + 518689 = 518712
  • 101 + 518611 = 518712
  • 179 + 518533 = 518712
  • 191 + 518521 = 518712
  • 239 + 518473 = 518712
  • 241 + 518471 = 518712
  • 281 + 518431 = 518712

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 518,712 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 518712 first appears in π at position 275,527 of the decimal expansion (the 275,527ordinal-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.
