Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521056, here are decompositions:

  • 5 + 521051 = 521056
  • 17 + 521039 = 521056
  • 47 + 521009 = 521056
  • 89 + 520967 = 521056
  • 113 + 520943 = 521056
  • 167 + 520889 = 521056
  • 269 + 520787 = 521056
  • 293 + 520763 = 521056

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 521,056 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 521056 first appears in π at position 257,413 of the decimal expansion (the 257,413ordinal-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.
