Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581576, here are decompositions:

  • 3 + 581573 = 581576
  • 19 + 581557 = 581576
  • 103 + 581473 = 581576
  • 199 + 581377 = 581576
  • 223 + 581353 = 581576
  • 283 + 581293 = 581576
  • 313 + 581263 = 581576
  • 337 + 581239 = 581576

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 581,576 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 581576 first appears in π at position 751,519 of the decimal expansion (the 751,519ordinal-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.
