Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490398, here are decompositions:

  • 5 + 490393 = 490398
  • 31 + 490367 = 490398
  • 59 + 490339 = 490398
  • 89 + 490309 = 490398
  • 127 + 490271 = 490398
  • 131 + 490267 = 490398
  • 149 + 490249 = 490398
  • 151 + 490247 = 490398

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 490,398 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 490398 first appears in π at position 6,727 of the decimal expansion (the 6,727ordinal-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.
