Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505260, here are decompositions:

  • 23 + 505237 = 505260
  • 29 + 505231 = 505260
  • 47 + 505213 = 505260
  • 59 + 505201 = 505260
  • 73 + 505187 = 505260
  • 79 + 505181 = 505260
  • 101 + 505159 = 505260
  • 103 + 505157 = 505260

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 505,260 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 505260 first appears in π at position 92,793 of the decimal expansion (the 92,793ordinal-suffix:rd 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.
