Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561008, here are decompositions:

  • 31 + 560977 = 561008
  • 67 + 560941 = 561008
  • 79 + 560929 = 561008
  • 139 + 560869 = 561008
  • 181 + 560827 = 561008
  • 211 + 560797 = 561008
  • 241 + 560767 = 561008
  • 271 + 560737 = 561008

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 561,008 and was likely granted around 1895.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 561008 first appears in π at position 497,210 of the decimal expansion (the 497,210ordinal-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.
