Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551598, here are decompositions:

5 + 31551593 = 31551598
11 + 31551587 = 31551598
59 + 31551539 = 31551598
101 + 31551497 = 31551598
137 + 31551461 = 31551598
167 + 31551431 = 31551598
191 + 31551407 = 31551598
251 + 31551347 = 31551598

Showing the first eight; more decompositions exist.
