Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626410, here are decompositions:

3 + 31626407 = 31626410
43 + 31626367 = 31626410
73 + 31626337 = 31626410
163 + 31626247 = 31626410
181 + 31626229 = 31626410
331 + 31626079 = 31626410
337 + 31626073 = 31626410
457 + 31625953 = 31626410

Showing the first eight; more decompositions exist.
