Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525122, here are decompositions:

  • 79 + 525043 = 525122
  • 109 + 525013 = 525122
  • 139 + 524983 = 525122
  • 151 + 524971 = 525122
  • 163 + 524959 = 525122
  • 181 + 524941 = 525122
  • 223 + 524899 = 525122
  • 229 + 524893 = 525122

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 525,122 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 525122 first appears in π at position 425,331 of the decimal expansion (the 425,331ordinal-suffix:st 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.
