Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567152, here are decompositions:

61 + 31567091 = 31567152
103 + 31567049 = 31567152
109 + 31567043 = 31567152
173 + 31566979 = 31567152
179 + 31566973 = 31567152
233 + 31566919 = 31567152
241 + 31566911 = 31567152
251 + 31566901 = 31567152

Showing the first eight; more decompositions exist.
