Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531022, here are decompositions:

  • 5 + 531017 = 531022
  • 53 + 530969 = 531022
  • 179 + 530843 = 531022
  • 269 + 530753 = 531022
  • 281 + 530741 = 531022
  • 311 + 530711 = 531022
  • 353 + 530669 = 531022
  • 419 + 530603 = 531022

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 531,022 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 531022 first appears in π at position 305,673 of the decimal expansion (the 305,673ordinal-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.
