Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581246, here are decompositions:

  • 7 + 581239 = 581246
  • 19 + 581227 = 581246
  • 73 + 581173 = 581246
  • 97 + 581149 = 581246
  • 103 + 581143 = 581246
  • 109 + 581137 = 581246
  • 157 + 581089 = 581246
  • 199 + 581047 = 581246

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 581,246 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 581246 first appears in π at position 88,630 of the decimal expansion (the 88,630ordinal-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.
