Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490256, here are decompositions:

  • 7 + 490249 = 490256
  • 73 + 490183 = 490256
  • 97 + 490159 = 490256
  • 139 + 490117 = 490256
  • 199 + 490057 = 490256
  • 223 + 490033 = 490256
  • 313 + 489943 = 490256
  • 409 + 489847 = 490256

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 490,256 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 490256 first appears in π at position 264,797 of the decimal expansion (the 264,797ordinal-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.
