Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491342, here are decompositions:

  • 3 + 491339 = 491342
  • 13 + 491329 = 491342
  • 43 + 491299 = 491342
  • 193 + 491149 = 491342
  • 283 + 491059 = 491342
  • 349 + 490993 = 491342
  • 373 + 490969 = 491342
  • 421 + 490921 = 491342

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 491,342 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 491342 first appears in π at position 302,692 of the decimal expansion (the 302,692ordinal-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.
