Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 585440, here are decompositions:

  • 3 + 585437 = 585440
  • 73 + 585367 = 585440
  • 103 + 585337 = 585440
  • 127 + 585313 = 585440
  • 151 + 585289 = 585440
  • 157 + 585283 = 585440
  • 223 + 585217 = 585440
  • 241 + 585199 = 585440

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 585,440 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 585440 first appears in π at position 408,622 of the decimal expansion (the 408,622ordinal-suffix:nd 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.
