Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40726, here are decompositions:

  • 17 + 40709 = 40726
  • 29 + 40697 = 40726
  • 89 + 40637 = 40726
  • 149 + 40577 = 40726
  • 167 + 40559 = 40726
  • 197 + 40529 = 40726
  • 227 + 40499 = 40726
  • 233 + 40493 = 40726

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40726 first appears in π at position 25,525 of the decimal expansion (the 25,525ordinal-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.
