Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626846, here are decompositions:

5 + 31626841 = 31626846
7 + 31626839 = 31626846
19 + 31626827 = 31626846
59 + 31626787 = 31626846
79 + 31626767 = 31626846
137 + 31626709 = 31626846
157 + 31626689 = 31626846
179 + 31626667 = 31626846

Showing the first eight; more decompositions exist.
