Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486138, here are decompositions:

  • 5 + 486133 = 486138
  • 19 + 486119 = 486138
  • 47 + 486091 = 486138
  • 67 + 486071 = 486138
  • 97 + 486041 = 486138
  • 101 + 486037 = 486138
  • 179 + 485959 = 486138
  • 197 + 485941 = 486138

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 486,138 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 486138 first appears in π at position 394,522 of the decimal expansion (the 394,522ordinal-suffix:nd 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.
