Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505904, here are decompositions:

  • 37 + 505867 = 505904
  • 127 + 505777 = 505904
  • 193 + 505711 = 505904
  • 211 + 505693 = 505904
  • 241 + 505663 = 505904
  • 271 + 505633 = 505904
  • 331 + 505573 = 505904
  • 367 + 505537 = 505904

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 505,904 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 505904 first appears in π at position 543,263 of the decimal expansion (the 543,263ordinal-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.
