Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8126, here are decompositions:

  • 3 + 8123 = 8126
  • 37 + 8089 = 8126
  • 67 + 8059 = 8126
  • 73 + 8053 = 8126
  • 109 + 8017 = 8126
  • 163 + 7963 = 8126
  • 193 + 7933 = 8126
  • 199 + 7927 = 8126

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8126 first appears in π at position 11,766 of the decimal expansion (the 11,766ordinal-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.
