Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551032, here are decompositions:

13 + 31551019 = 31551032
109 + 31550923 = 31551032
181 + 31550851 = 31551032
199 + 31550833 = 31551032
229 + 31550803 = 31551032
241 + 31550791 = 31551032
421 + 31550611 = 31551032
433 + 31550599 = 31551032

Showing the first eight; more decompositions exist.
