Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561078, here are decompositions:

  • 17 + 561061 = 561078
  • 19 + 561059 = 561078
  • 31 + 561047 = 561078
  • 59 + 561019 = 561078
  • 101 + 560977 = 561078
  • 109 + 560969 = 561078
  • 137 + 560941 = 561078
  • 139 + 560939 = 561078

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 561,078 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 561078 first appears in π at position 498,854 of the decimal expansion (the 498,854ordinal-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.
