Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626402, here are decompositions:

13 + 31626389 = 31626402
19 + 31626383 = 31626402
43 + 31626359 = 31626402
79 + 31626323 = 31626402
173 + 31626229 = 31626402
193 + 31626209 = 31626402
211 + 31626191 = 31626402
271 + 31626131 = 31626402

Showing the first eight; more decompositions exist.
