Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494420, here are decompositions:

  • 7 + 494413 = 494420
  • 13 + 494407 = 494420
  • 37 + 494383 = 494420
  • 61 + 494359 = 494420
  • 67 + 494353 = 494420
  • 79 + 494341 = 494420
  • 103 + 494317 = 494420
  • 139 + 494281 = 494420

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 494,420 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 494420 first appears in π at position 935,226 of the decimal expansion (the 935,226ordinal-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.
