Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494818, here are decompositions:

  • 29 + 494789 = 494818
  • 59 + 494759 = 494818
  • 131 + 494687 = 494818
  • 167 + 494651 = 494818
  • 179 + 494639 = 494818
  • 197 + 494621 = 494818
  • 227 + 494591 = 494818
  • 251 + 494567 = 494818

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 494,818 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 494818 first appears in π at position 219,254 of the decimal expansion (the 219,254ordinal-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.
