Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576252, here are decompositions:

11 + 31576241 = 31576252
41 + 31576211 = 31576252
53 + 31576199 = 31576252
83 + 31576169 = 31576252
89 + 31576163 = 31576252
131 + 31576121 = 31576252
251 + 31576001 = 31576252
353 + 31575899 = 31576252

Showing the first eight; more decompositions exist.
