Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505864, here are decompositions:

  • 41 + 505823 = 505864
  • 53 + 505811 = 505864
  • 83 + 505781 = 505864
  • 101 + 505763 = 505864
  • 137 + 505727 = 505864
  • 173 + 505691 = 505864
  • 251 + 505613 = 505864
  • 257 + 505607 = 505864

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 505,864 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 505864 first appears in π at position 835,832 of the decimal expansion (the 835,832ordinal-suffix:nd 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.
