Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72706, here are decompositions:

  • 5 + 72701 = 72706
  • 17 + 72689 = 72706
  • 59 + 72647 = 72706
  • 83 + 72623 = 72706
  • 89 + 72617 = 72706
  • 173 + 72533 = 72706
  • 239 + 72467 = 72706
  • 353 + 72353 = 72706

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 72706 first appears in π at position 13,030 of the decimal expansion (the 13,030ordinal-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.
