Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525812, here are decompositions:

  • 3 + 525809 = 525812
  • 31 + 525781 = 525812
  • 43 + 525769 = 525812
  • 73 + 525739 = 525812
  • 103 + 525709 = 525812
  • 163 + 525649 = 525812
  • 229 + 525583 = 525812
  • 241 + 525571 = 525812

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 525,812 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 525812 first appears in π at position 396,251 of the decimal expansion (the 396,251ordinal-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.
