Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492638, here are decompositions:

  • 7 + 492631 = 492638
  • 19 + 492619 = 492638
  • 37 + 492601 = 492638
  • 127 + 492511 = 492638
  • 151 + 492487 = 492638
  • 229 + 492409 = 492638
  • 241 + 492397 = 492638
  • 571 + 492067 = 492638

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 492,638 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 492638 first appears in π at position 567,116 of the decimal expansion (the 567,116ordinal-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.
