Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505284, here are decompositions:

  • 5 + 505279 = 505284
  • 7 + 505277 = 505284
  • 47 + 505237 = 505284
  • 53 + 505231 = 505284
  • 71 + 505213 = 505284
  • 83 + 505201 = 505284
  • 97 + 505187 = 505284
  • 103 + 505181 = 505284

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 505,284 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 505284 first appears in π at position 620,281 of the decimal expansion (the 620,281ordinal-suffix:st 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.
