Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8182, here are decompositions:

  • 3 + 8179 = 8182
  • 11 + 8171 = 8182
  • 59 + 8123 = 8182
  • 71 + 8111 = 8182
  • 89 + 8093 = 8182
  • 101 + 8081 = 8182
  • 113 + 8069 = 8182
  • 173 + 8009 = 8182

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8182 first appears in π at position 1,034 of the decimal expansion (the 1,034ordinal-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.
