Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581190, here are decompositions:

  • 7 + 581183 = 581190
  • 13 + 581177 = 581190
  • 17 + 581173 = 581190
  • 19 + 581171 = 581190
  • 41 + 581149 = 581190
  • 47 + 581143 = 581190
  • 53 + 581137 = 581190
  • 89 + 581101 = 581190

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 581,190 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 581190 first appears in π at position 624,430 of the decimal expansion (the 624,430ordinal-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.
