Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494478, here are decompositions:

  • 7 + 494471 = 494478
  • 37 + 494441 = 494478
  • 71 + 494407 = 494478
  • 97 + 494381 = 494478
  • 109 + 494369 = 494478
  • 137 + 494341 = 494478
  • 151 + 494327 = 494478
  • 191 + 494287 = 494478

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 494,478 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 494478 first appears in π at position 570,785 of the decimal expansion (the 570,785ordinal-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.
