Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493870, here are decompositions:

  • 11 + 493859 = 493870
  • 17 + 493853 = 493870
  • 53 + 493817 = 493870
  • 59 + 493811 = 493870
  • 137 + 493733 = 493870
  • 149 + 493721 = 493870
  • 227 + 493643 = 493870
  • 263 + 493607 = 493870

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 493,870 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 493870 first appears in π at position 781,333 of the decimal expansion (the 781,333ordinal-suffix:rd 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.
