Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551606, here are decompositions:

7 + 31551599 = 31551606
13 + 31551593 = 31551606
19 + 31551587 = 31551606
29 + 31551577 = 31551606
59 + 31551547 = 31551606
67 + 31551539 = 31551606
89 + 31551517 = 31551606
103 + 31551503 = 31551606

Showing the first eight; more decompositions exist.
