Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581882, here are decompositions:

  • 13 + 581869 = 581882
  • 19 + 581863 = 581882
  • 61 + 581821 = 581882
  • 73 + 581809 = 581882
  • 109 + 581773 = 581882
  • 139 + 581743 = 581882
  • 151 + 581731 = 581882
  • 181 + 581701 = 581882

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 581,882 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 581882 first appears in π at position 695,997 of the decimal expansion (the 695,997ordinal-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.
