Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581262, here are decompositions:

  • 23 + 581239 = 581262
  • 61 + 581201 = 581262
  • 79 + 581183 = 581262
  • 89 + 581173 = 581262
  • 113 + 581149 = 581262
  • 163 + 581099 = 581262
  • 173 + 581089 = 581262
  • 191 + 581071 = 581262

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 581,262 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 581262 first appears in π at position 62,338 of the decimal expansion (the 62,338ordinal-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.
