Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520920, here are decompositions:

  • 7 + 520913 = 520920
  • 31 + 520889 = 520920
  • 53 + 520867 = 520920
  • 67 + 520853 = 520920
  • 79 + 520841 = 520920
  • 83 + 520837 = 520920
  • 107 + 520813 = 520920
  • 157 + 520763 = 520920

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 520,920 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 520920 first appears in π at position 325 of the decimal expansion (the 325ordinal-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.
