Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505790, here are decompositions:

  • 13 + 505777 = 505790
  • 31 + 505759 = 505790
  • 79 + 505711 = 505790
  • 97 + 505693 = 505790
  • 127 + 505663 = 505790
  • 151 + 505639 = 505790
  • 157 + 505633 = 505790
  • 277 + 505513 = 505790

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 505,790 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 505790 first appears in π at position 619,738 of the decimal expansion (the 619,738ordinal-suffix:th 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.
