Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525566, here are decompositions:

  • 37 + 525529 = 525566
  • 73 + 525493 = 525566
  • 109 + 525457 = 525566
  • 127 + 525439 = 525566
  • 157 + 525409 = 525566
  • 193 + 525373 = 525566
  • 313 + 525253 = 525566
  • 367 + 525199 = 525566

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 525,566 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 525566 first appears in π at position 671,703 of the decimal expansion (the 671,703ordinal-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.
