Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525548, here are decompositions:

11 + 31525537 = 31525548
59 + 31525489 = 31525548
71 + 31525477 = 31525548
101 + 31525447 = 31525548
127 + 31525421 = 31525548
151 + 31525397 = 31525548
181 + 31525367 = 31525548
269 + 31525279 = 31525548

Showing the first eight; more decompositions exist.
