Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494170, here are decompositions:

  • 3 + 494167 = 494170
  • 23 + 494147 = 494170
  • 29 + 494141 = 494170
  • 41 + 494129 = 494170
  • 101 + 494069 = 494170
  • 191 + 493979 = 494170
  • 197 + 493973 = 494170
  • 233 + 493937 = 494170

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 494,170 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 494170 first appears in π at position 189,042 of the decimal expansion (the 189,042ordinal-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.
