Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551414, here are decompositions:

5 + 31551409 = 31551414
7 + 31551407 = 31551414
53 + 31551361 = 31551414
61 + 31551353 = 31551414
67 + 31551347 = 31551414
73 + 31551341 = 31551414
107 + 31551307 = 31551414
131 + 31551283 = 31551414

Showing the first eight; more decompositions exist.
