Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525918, here are decompositions:

  • 5 + 525913 = 525918
  • 31 + 525887 = 525918
  • 47 + 525871 = 525918
  • 79 + 525839 = 525918
  • 101 + 525817 = 525918
  • 109 + 525809 = 525918
  • 137 + 525781 = 525918
  • 149 + 525769 = 525918

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 525,918 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 525918 first appears in π at position 287,033 of the decimal expansion (the 287,033ordinal-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.
