Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505042, here are decompositions:

  • 11 + 505031 = 505042
  • 53 + 504989 = 505042
  • 59 + 504983 = 505042
  • 89 + 504953 = 505042
  • 113 + 504929 = 505042
  • 149 + 504893 = 505042
  • 191 + 504851 = 505042
  • 359 + 504683 = 505042

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 505,042 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 505042 first appears in π at position 668,323 of the decimal expansion (the 668,323ordinal-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.
