Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2056, here are decompositions:

  • 3 + 2053 = 2056
  • 17 + 2039 = 2056
  • 29 + 2027 = 2056
  • 53 + 2003 = 2056
  • 59 + 1997 = 2056
  • 83 + 1973 = 2056
  • 107 + 1949 = 2056
  • 149 + 1907 = 2056

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2056 first appears in π at position 1,326 of the decimal expansion (the 1,326ordinal-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.
