Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576152, here are decompositions:

31 + 31576121 = 31576152
61 + 31576091 = 31576152
103 + 31576049 = 31576152
149 + 31576003 = 31576152
151 + 31576001 = 31576152
229 + 31575923 = 31576152
271 + 31575881 = 31576152
313 + 31575839 = 31576152

Showing the first eight; more decompositions exist.
