Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501688, here are decompositions:

  • 29 + 501659 = 501688
  • 71 + 501617 = 501688
  • 269 + 501419 = 501688
  • 347 + 501341 = 501688
  • 389 + 501299 = 501688
  • 401 + 501287 = 501688
  • 431 + 501257 = 501688
  • 479 + 501209 = 501688

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 501,688 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 501688 first appears in π at position 413,214 of the decimal expansion (the 413,214ordinal-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.
