Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523964, here are decompositions:

11 + 31523953 = 31523964
23 + 31523941 = 31523964
47 + 31523917 = 31523964
83 + 31523881 = 31523964
113 + 31523851 = 31523964
163 + 31523801 = 31523964
211 + 31523753 = 31523964
257 + 31523707 = 31523964

Showing the first eight; more decompositions exist.
