Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71090, here are decompositions:

  • 31 + 71059 = 71090
  • 67 + 71023 = 71090
  • 79 + 71011 = 71090
  • 109 + 70981 = 71090
  • 139 + 70951 = 71090
  • 199 + 70891 = 71090
  • 211 + 70879 = 71090
  • 223 + 70867 = 71090

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71090 first appears in π at position 22,302 of the decimal expansion (the 22,302ordinal-suffix:nd 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.
