Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551634, here are decompositions:

5 + 31551629 = 31551634
41 + 31551593 = 31551634
47 + 31551587 = 31551634
131 + 31551503 = 31551634
137 + 31551497 = 31551634
173 + 31551461 = 31551634
197 + 31551437 = 31551634
227 + 31551407 = 31551634

Showing the first eight; more decompositions exist.
