Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518552, here are decompositions:

11 + 31518541 = 31518552
29 + 31518523 = 31518552
31 + 31518521 = 31518552
61 + 31518491 = 31518552
71 + 31518481 = 31518552
101 + 31518451 = 31518552
173 + 31518379 = 31518552
199 + 31518353 = 31518552

Showing the first eight; more decompositions exist.
