Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494442, here are decompositions:

  • 29 + 494413 = 494442
  • 59 + 494383 = 494442
  • 61 + 494381 = 494442
  • 73 + 494369 = 494442
  • 83 + 494359 = 494442
  • 89 + 494353 = 494442
  • 101 + 494341 = 494442
  • 173 + 494269 = 494442

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 494,442 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 494442 first appears in π at position 336,963 of the decimal expansion (the 336,963ordinal-suffix:rd 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.
