Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626954, here are decompositions:

11 + 31626943 = 31626954
61 + 31626893 = 31626954
71 + 31626883 = 31626954
97 + 31626857 = 31626954
113 + 31626841 = 31626954
127 + 31626827 = 31626954
157 + 31626797 = 31626954
167 + 31626787 = 31626954

Showing the first eight; more decompositions exist.
