Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516490, here are decompositions:

  • 41 + 516449 = 516490
  • 53 + 516437 = 516490
  • 59 + 516431 = 516490
  • 83 + 516407 = 516490
  • 113 + 516377 = 516490
  • 131 + 516359 = 516490
  • 167 + 516323 = 516490
  • 197 + 516293 = 516490

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 516,490 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 516490 first appears in π at position 89,959 of the decimal expansion (the 89,959ordinal-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.
