Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561270, here are decompositions:

  • 19 + 561251 = 561270
  • 41 + 561229 = 561270
  • 71 + 561199 = 561270
  • 79 + 561191 = 561270
  • 89 + 561181 = 561270
  • 97 + 561173 = 561270
  • 109 + 561161 = 561270
  • 167 + 561103 = 561270

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 561,270 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 561270 first appears in π at position 613,154 of the decimal expansion (the 613,154ordinal-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.
