Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561316, here are decompositions:

  • 3 + 561313 = 561316
  • 233 + 561083 = 561316
  • 257 + 561059 = 561316
  • 263 + 561053 = 561316
  • 269 + 561047 = 561316
  • 347 + 560969 = 561316
  • 419 + 560897 = 561316
  • 443 + 560873 = 561316

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 561,316 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 561316 first appears in π at position 54,688 of the decimal expansion (the 54,688ordinal-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.
