Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627046, here are decompositions:

13 + 31627033 = 31627046
19 + 31627027 = 31627046
67 + 31626979 = 31627046
79 + 31626967 = 31627046
103 + 31626943 = 31627046
163 + 31626883 = 31627046
337 + 31626709 = 31627046
379 + 31626667 = 31627046

Showing the first eight; more decompositions exist.
