Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536948, here are decompositions:

5 + 31536943 = 31536948
11 + 31536937 = 31536948
31 + 31536917 = 31536948
101 + 31536847 = 31536948
127 + 31536821 = 31536948
229 + 31536719 = 31536948
241 + 31536707 = 31536948
251 + 31536697 = 31536948

Showing the first eight; more decompositions exist.
