Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551462, here are decompositions:

11 + 31551451 = 31551462
31 + 31551431 = 31551462
53 + 31551409 = 31551462
101 + 31551361 = 31551462
109 + 31551353 = 31551462
113 + 31551349 = 31551462
179 + 31551283 = 31551462
181 + 31551281 = 31551462

Showing the first eight; more decompositions exist.
