Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626798, here are decompositions:

11 + 31626787 = 31626798
31 + 31626767 = 31626798
89 + 31626709 = 31626798
107 + 31626691 = 31626798
109 + 31626689 = 31626798
131 + 31626667 = 31626798
179 + 31626619 = 31626798
191 + 31626607 = 31626798

Showing the first eight; more decompositions exist.
