Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581344, here are decompositions:

  • 3 + 581341 = 581344
  • 11 + 581333 = 581344
  • 41 + 581303 = 581344
  • 83 + 581261 = 581344
  • 107 + 581237 = 581344
  • 167 + 581177 = 581344
  • 173 + 581171 = 581344
  • 347 + 580997 = 581344

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 581,344 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 581344 first appears in π at position 41,708 of the decimal expansion (the 41,708ordinal-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.
