Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493866, here are decompositions:

  • 7 + 493859 = 493866
  • 13 + 493853 = 493866
  • 53 + 493813 = 493866
  • 59 + 493807 = 493866
  • 73 + 493793 = 493866
  • 89 + 493777 = 493866
  • 137 + 493729 = 493866
  • 157 + 493709 = 493866

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 493,866 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 493866 first appears in π at position 904,908 of the decimal expansion (the 904,908ordinal-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.
