Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628352, here are decompositions:

11 + 31628341 = 31628352
61 + 31628291 = 31628352
79 + 31628273 = 31628352
83 + 31628269 = 31628352
103 + 31628249 = 31628352
113 + 31628239 = 31628352
179 + 31628173 = 31628352
181 + 31628171 = 31628352

Showing the first eight; more decompositions exist.
