Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493988, here are decompositions:

  • 181 + 493807 = 493988
  • 211 + 493777 = 493988
  • 241 + 493747 = 493988
  • 277 + 493711 = 493988
  • 331 + 493657 = 493988
  • 367 + 493621 = 493988
  • 409 + 493579 = 493988
  • 421 + 493567 = 493988

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 493,988 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 493988 first appears in π at position 816,140 of the decimal expansion (the 816,140ordinal-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.
