Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531194, here are decompositions:

  • 31 + 531163 = 531194
  • 61 + 531133 = 531194
  • 73 + 531121 = 531194
  • 151 + 531043 = 531194
  • 211 + 530983 = 531194
  • 283 + 530911 = 531194
  • 337 + 530857 = 531194
  • 397 + 530797 = 531194

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 531,194 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 531194 first appears in π at position 963,503 of the decimal expansion (the 963,503ordinal-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.
