Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523648, here are decompositions:

  • 11 + 523637 = 523648
  • 17 + 523631 = 523648
  • 71 + 523577 = 523648
  • 107 + 523541 = 523648
  • 137 + 523511 = 523648
  • 479 + 523169 = 523648
  • 599 + 523049 = 523648
  • 617 + 523031 = 523648

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 523,648 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 523648 first appears in π at position 121,363 of the decimal expansion (the 121,363ordinal-suffix:rd 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.
