Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505824, here are decompositions:

  • 5 + 505819 = 505824
  • 13 + 505811 = 505824
  • 43 + 505781 = 505824
  • 47 + 505777 = 505824
  • 61 + 505763 = 505824
  • 97 + 505727 = 505824
  • 113 + 505711 = 505824
  • 131 + 505693 = 505824

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 505,824 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 505824 first appears in π at position 919,821 of the decimal expansion (the 919,821ordinal-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.
