Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523304, here are decompositions:

11 + 31523293 = 31523304
37 + 31523267 = 31523304
53 + 31523251 = 31523304
61 + 31523243 = 31523304
67 + 31523237 = 31523304
73 + 31523231 = 31523304
83 + 31523221 = 31523304
97 + 31523207 = 31523304

Showing the first eight; more decompositions exist.
