Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517488, here are decompositions:

  • 7 + 517481 = 517488
  • 17 + 517471 = 517488
  • 19 + 517469 = 517488
  • 29 + 517459 = 517488
  • 31 + 517457 = 517488
  • 71 + 517417 = 517488
  • 89 + 517399 = 517488
  • 107 + 517381 = 517488

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 517,488 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 517488 first appears in π at position 741,885 of the decimal expansion (the 741,885ordinal-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.
