Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520828, here are decompositions:

  • 41 + 520787 = 520828
  • 107 + 520721 = 520828
  • 137 + 520691 = 520828
  • 149 + 520679 = 520828
  • 179 + 520649 = 520828
  • 197 + 520631 = 520828
  • 239 + 520589 = 520828
  • 257 + 520571 = 520828

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 520,828 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 520828 first appears in π at position 236,037 of the decimal expansion (the 236,037ordinal-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.
