Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494128, here are decompositions:

  • 59 + 494069 = 494128
  • 149 + 493979 = 494128
  • 191 + 493937 = 494128
  • 197 + 493931 = 494128
  • 251 + 493877 = 494128
  • 269 + 493859 = 494128
  • 311 + 493817 = 494128
  • 317 + 493811 = 494128

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 494,128 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 494128 first appears in π at position 764,166 of the decimal expansion (the 764,166ordinal-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.
