Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505256, here are decompositions:

  • 19 + 505237 = 505256
  • 43 + 505213 = 505256
  • 97 + 505159 = 505256
  • 127 + 505129 = 505256
  • 139 + 505117 = 505256
  • 223 + 505033 = 505256
  • 229 + 505027 = 505256
  • 313 + 504943 = 505256

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 505,256 and was likely granted around 1893.

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

Position in π

The digit sequence 505256 first appears in π at position 871,310 of the decimal expansion (the 871,310ordinal-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.
