Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523264, here are decompositions:

13 + 31523251 = 31523264
37 + 31523227 = 31523264
43 + 31523221 = 31523264
103 + 31523161 = 31523264
151 + 31523113 = 31523264
211 + 31523053 = 31523264
277 + 31522987 = 31523264
313 + 31522951 = 31523264

Showing the first eight; more decompositions exist.
