Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581354, here are decompositions:

  • 3 + 581351 = 581354
  • 13 + 581341 = 581354
  • 31 + 581323 = 581354
  • 43 + 581311 = 581354
  • 61 + 581293 = 581354
  • 127 + 581227 = 581354
  • 157 + 581197 = 581354
  • 181 + 581173 = 581354

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 581,354 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 581354 first appears in π at position 439,023 of the decimal expansion (the 439,023ordinal-suffix:rd 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.
