Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581254, here are decompositions:

  • 17 + 581237 = 581254
  • 53 + 581201 = 581254
  • 71 + 581183 = 581254
  • 83 + 581171 = 581254
  • 257 + 580997 = 581254
  • 353 + 580901 = 581254
  • 383 + 580871 = 581254
  • 461 + 580793 = 581254

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 581,254 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 581254 first appears in π at position 750,699 of the decimal expansion (the 750,699ordinal-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.
