Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531994, here are decompositions:

  • 5 + 531989 = 531994
  • 11 + 531983 = 531994
  • 17 + 531977 = 531994
  • 83 + 531911 = 531994
  • 131 + 531863 = 531994
  • 137 + 531857 = 531994
  • 167 + 531827 = 531994
  • 173 + 531821 = 531994

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 531,994 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 531994 first appears in π at position 755,424 of the decimal expansion (the 755,424ordinal-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.
