Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490406, here are decompositions:

  • 13 + 490393 = 490406
  • 67 + 490339 = 490406
  • 97 + 490309 = 490406
  • 139 + 490267 = 490406
  • 157 + 490249 = 490406
  • 199 + 490207 = 490406
  • 223 + 490183 = 490406
  • 349 + 490057 = 490406

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 490,406 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 490406 first appears in π at position 334,995 of the decimal expansion (the 334,995ordinal-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.
