Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494512, here are decompositions:

  • 41 + 494471 = 494512
  • 71 + 494441 = 494512
  • 131 + 494381 = 494512
  • 383 + 494129 = 494512
  • 419 + 494093 = 494512
  • 443 + 494069 = 494512
  • 461 + 494051 = 494512
  • 593 + 493919 = 494512

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 494,512 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 494512 first appears in π at position 917,926 of the decimal expansion (the 917,926ordinal-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.
