Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10256, here are decompositions:

  • 3 + 10253 = 10256
  • 13 + 10243 = 10256
  • 79 + 10177 = 10256
  • 97 + 10159 = 10256
  • 157 + 10099 = 10256
  • 163 + 10093 = 10256
  • 283 + 9973 = 10256
  • 307 + 9949 = 10256

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10256 first appears in π at position 70,758 of the decimal expansion (the 70,758ordinal-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.
