Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525720, here are decompositions:

  • 7 + 525713 = 525720
  • 11 + 525709 = 525720
  • 23 + 525697 = 525720
  • 43 + 525677 = 525720
  • 71 + 525649 = 525720
  • 79 + 525641 = 525720
  • 113 + 525607 = 525720
  • 127 + 525593 = 525720

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 525,720 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 525720 first appears in π at position 1,005 of the decimal expansion (the 1,005ordinal-suffix:th 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.
