Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490518, here are decompositions:

  • 19 + 490499 = 490518
  • 37 + 490481 = 490518
  • 59 + 490459 = 490518
  • 97 + 490421 = 490518
  • 101 + 490417 = 490518
  • 151 + 490367 = 490518
  • 179 + 490339 = 490518
  • 241 + 490277 = 490518

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 490,518 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 490518 first appears in π at position 290,141 of the decimal expansion (the 290,141ordinal-suffix:st 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.
