Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490288, here are decompositions:

  • 5 + 490283 = 490288
  • 11 + 490277 = 490288
  • 17 + 490271 = 490288
  • 41 + 490247 = 490288
  • 47 + 490241 = 490288
  • 137 + 490151 = 490288
  • 167 + 490121 = 490288
  • 191 + 490097 = 490288

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 490,288 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 490288 first appears in π at position 39,746 of the decimal expansion (the 39,746ordinal-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.
