Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525228, here are decompositions:

  • 7 + 525221 = 525228
  • 19 + 525209 = 525228
  • 29 + 525199 = 525228
  • 37 + 525191 = 525228
  • 61 + 525167 = 525228
  • 71 + 525157 = 525228
  • 101 + 525127 = 525228
  • 127 + 525101 = 525228

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 525,228 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 525228 first appears in π at position 15,043 of the decimal expansion (the 15,043ordinal-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.
