Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519626, here are decompositions:

  • 7 + 519619 = 519626
  • 73 + 519553 = 519626
  • 103 + 519523 = 519626
  • 127 + 519499 = 519626
  • 139 + 519487 = 519626
  • 193 + 519433 = 519626
  • 199 + 519427 = 519626
  • 277 + 519349 = 519626

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 519,626 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 519626 first appears in π at position 803,831 of the decimal expansion (the 803,831ordinal-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.
