Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525920, here are decompositions:

  • 7 + 525913 = 525920
  • 103 + 525817 = 525920
  • 139 + 525781 = 525920
  • 151 + 525769 = 525920
  • 181 + 525739 = 525920
  • 193 + 525727 = 525920
  • 211 + 525709 = 525920
  • 223 + 525697 = 525920

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 525,920 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 525920 first appears in π at position 159,777 of the decimal expansion (the 159,777ordinal-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.
