Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71066, here are decompositions:

  • 7 + 71059 = 71066
  • 43 + 71023 = 71066
  • 67 + 70999 = 71066
  • 97 + 70969 = 71066
  • 109 + 70957 = 71066
  • 199 + 70867 = 71066
  • 223 + 70843 = 71066
  • 283 + 70783 = 71066

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71066 first appears in π at position 38,129 of the decimal expansion (the 38,129ordinal-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.
