Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551694, here are decompositions:

11 + 31551683 = 31551694
23 + 31551671 = 31551694
101 + 31551593 = 31551694
107 + 31551587 = 31551694
191 + 31551503 = 31551694
197 + 31551497 = 31551694
233 + 31551461 = 31551694
257 + 31551437 = 31551694

Showing the first eight; more decompositions exist.
