Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42706, here are decompositions:

  • 3 + 42703 = 42706
  • 5 + 42701 = 42706
  • 17 + 42689 = 42706
  • 23 + 42683 = 42706
  • 29 + 42677 = 42706
  • 137 + 42569 = 42706
  • 149 + 42557 = 42706
  • 173 + 42533 = 42706

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42706 first appears in π at position 130,852 of the decimal expansion (the 130,852ordinal-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.
