Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559028, here are decompositions:

31 + 31558997 = 31559028
71 + 31558957 = 31559028
89 + 31558939 = 31559028
101 + 31558927 = 31559028
131 + 31558897 = 31559028
181 + 31558847 = 31559028
197 + 31558831 = 31559028
229 + 31558799 = 31559028

Showing the first eight; more decompositions exist.
