Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581612, here are decompositions:

  • 13 + 581599 = 581612
  • 61 + 581551 = 581612
  • 139 + 581473 = 581612
  • 271 + 581341 = 581612
  • 349 + 581263 = 581612
  • 373 + 581239 = 581612
  • 439 + 581173 = 581612
  • 463 + 581149 = 581612

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 581,612 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 581612 first appears in π at position 38,170 of the decimal expansion (the 38,170ordinal-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.
