Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523690, here are decompositions:

  • 17 + 523673 = 523690
  • 23 + 523667 = 523690
  • 53 + 523637 = 523690
  • 59 + 523631 = 523690
  • 113 + 523577 = 523690
  • 137 + 523553 = 523690
  • 149 + 523541 = 523690
  • 179 + 523511 = 523690

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 523,690 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 523690 first appears in π at position 518,334 of the decimal expansion (the 518,334ordinal-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.
