Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518604, here are decompositions:

  • 7 + 518597 = 518604
  • 17 + 518587 = 518604
  • 61 + 518543 = 518604
  • 71 + 518533 = 518604
  • 83 + 518521 = 518604
  • 131 + 518473 = 518604
  • 137 + 518467 = 518604
  • 157 + 518447 = 518604

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 518,604 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 518604 first appears in π at position 181,141 of the decimal expansion (the 181,141ordinal-suffix:st 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.
