Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71028, here are decompositions:

  • 5 + 71023 = 71028
  • 17 + 71011 = 71028
  • 29 + 70999 = 71028
  • 31 + 70997 = 71028
  • 37 + 70991 = 71028
  • 47 + 70981 = 71028
  • 59 + 70969 = 71028
  • 71 + 70957 = 71028

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71028 first appears in π at position 8,003 of the decimal expansion (the 8,003ordinal-suffix:rd 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.
