Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505090, here are decompositions:

  • 17 + 505073 = 505090
  • 23 + 505067 = 505090
  • 29 + 505061 = 505090
  • 41 + 505049 = 505090
  • 59 + 505031 = 505090
  • 101 + 504989 = 505090
  • 107 + 504983 = 505090
  • 137 + 504953 = 505090

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 505,090 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 505090 first appears in π at position 543,428 of the decimal expansion (the 543,428ordinal-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.
