Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626996, here are decompositions:

17 + 31626979 = 31626996
19 + 31626977 = 31626996
29 + 31626967 = 31626996
53 + 31626943 = 31626996
97 + 31626899 = 31626996
103 + 31626893 = 31626996
113 + 31626883 = 31626996
127 + 31626869 = 31626996

Showing the first eight; more decompositions exist.
