Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531304, here are decompositions:

  • 5 + 531299 = 531304
  • 17 + 531287 = 531304
  • 23 + 531281 = 531304
  • 41 + 531263 = 531304
  • 101 + 531203 = 531304
  • 107 + 531197 = 531304
  • 131 + 531173 = 531304
  • 233 + 531071 = 531304

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 531,304 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 531304 first appears in π at position 166,590 of the decimal expansion (the 166,590ordinal-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.
