Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581232, here are decompositions:

  • 5 + 581227 = 581232
  • 31 + 581201 = 581232
  • 59 + 581173 = 581232
  • 61 + 581171 = 581232
  • 83 + 581149 = 581232
  • 89 + 581143 = 581232
  • 131 + 581101 = 581232
  • 163 + 581069 = 581232

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 581,232 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 581232 first appears in π at position 211,419 of the decimal expansion (the 211,419ordinal-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.
