Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525690, here are decompositions:

  • 13 + 525677 = 525690
  • 19 + 525671 = 525690
  • 41 + 525649 = 525690
  • 83 + 525607 = 525690
  • 97 + 525593 = 525690
  • 107 + 525583 = 525690
  • 149 + 525541 = 525690
  • 157 + 525533 = 525690

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 525,690 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 525690 first appears in π at position 581,643 of the decimal expansion (the 581,643ordinal-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.
