Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490874, here are decompositions:

  • 37 + 490837 = 490874
  • 103 + 490771 = 490874
  • 211 + 490663 = 490874
  • 283 + 490591 = 490874
  • 331 + 490543 = 490874
  • 337 + 490537 = 490874
  • 421 + 490453 = 490874
  • 457 + 490417 = 490874

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 490,874 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 490874 first appears in π at position 130,889 of the decimal expansion (the 130,889ordinal-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.
