Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626726, here are decompositions:

17 + 31626709 = 31626726
37 + 31626689 = 31626726
59 + 31626667 = 31626726
107 + 31626619 = 31626726
137 + 31626589 = 31626726
163 + 31626563 = 31626726
179 + 31626547 = 31626726
193 + 31626533 = 31626726

Showing the first eight; more decompositions exist.
