Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626516, here are decompositions:

17 + 31626499 = 31626516
23 + 31626493 = 31626516
79 + 31626437 = 31626516
109 + 31626407 = 31626516
127 + 31626389 = 31626516
139 + 31626377 = 31626516
149 + 31626367 = 31626516
157 + 31626359 = 31626516

Showing the first eight; more decompositions exist.
