Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581758, here are decompositions:

  • 5 + 581753 = 581758
  • 29 + 581729 = 581758
  • 59 + 581699 = 581758
  • 71 + 581687 = 581758
  • 101 + 581657 = 581758
  • 311 + 581447 = 581758
  • 347 + 581411 = 581758
  • 389 + 581369 = 581758

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 581,758 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 581758 first appears in π at position 478,990 of the decimal expansion (the 478,990ordinal-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.
