Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516540, here are decompositions:

  • 19 + 516521 = 516540
  • 23 + 516517 = 516540
  • 41 + 516499 = 516540
  • 47 + 516493 = 516540
  • 71 + 516469 = 516540
  • 83 + 516457 = 516540
  • 103 + 516437 = 516540
  • 107 + 516433 = 516540

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 516,540 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 516540 first appears in π at position 871,744 of the decimal expansion (the 871,744ordinal-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.
