Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581684, here are decompositions:

  • 67 + 581617 = 581684
  • 127 + 581557 = 581684
  • 157 + 581527 = 581684
  • 163 + 581521 = 581684
  • 193 + 581491 = 581684
  • 211 + 581473 = 581684
  • 241 + 581443 = 581684
  • 277 + 581407 = 581684

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 581,684 and was likely granted around 1896.

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

Position in π

The digit sequence 581684 first appears in π at position 359,060 of the decimal expansion (the 359,060ordinal-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.
