Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505100, here are decompositions:

  • 3 + 505097 = 505100
  • 67 + 505033 = 505100
  • 73 + 505027 = 505100
  • 109 + 504991 = 505100
  • 157 + 504943 = 505100
  • 163 + 504937 = 505100
  • 199 + 504901 = 505100
  • 223 + 504877 = 505100

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 505,100 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 505100 first appears in π at position 622,024 of the decimal expansion (the 622,024ordinal-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.
