Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505020, here are decompositions:

  • 29 + 504991 = 505020
  • 31 + 504989 = 505020
  • 37 + 504983 = 505020
  • 53 + 504967 = 505020
  • 67 + 504953 = 505020
  • 73 + 504947 = 505020
  • 83 + 504937 = 505020
  • 127 + 504893 = 505020

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 505,020 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 505020 first appears in π at position 39,112 of the decimal expansion (the 39,112ordinal-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.
