Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626606, here are decompositions:

17 + 31626589 = 31626606
43 + 31626563 = 31626606
59 + 31626547 = 31626606
73 + 31626533 = 31626606
107 + 31626499 = 31626606
113 + 31626493 = 31626606
199 + 31626407 = 31626606
223 + 31626383 = 31626606

Showing the first eight; more decompositions exist.
