Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481490, here are decompositions:

  • 43 + 481447 = 481490
  • 73 + 481417 = 481490
  • 103 + 481387 = 481490
  • 127 + 481363 = 481490
  • 193 + 481297 = 481490
  • 241 + 481249 = 481490
  • 283 + 481207 = 481490
  • 313 + 481177 = 481490

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 481,490 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 481490 first appears in π at position 505,929 of the decimal expansion (the 505,929ordinal-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.
