Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626396, here are decompositions:

7 + 31626389 = 31626396
13 + 31626383 = 31626396
19 + 31626377 = 31626396
29 + 31626367 = 31626396
37 + 31626359 = 31626396
59 + 31626337 = 31626396
73 + 31626323 = 31626396
149 + 31626247 = 31626396

Showing the first eight; more decompositions exist.
