Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550132, here are decompositions:

13 + 31550119 = 31550132
151 + 31549981 = 31550132
199 + 31549933 = 31550132
241 + 31549891 = 31550132
331 + 31549801 = 31550132
379 + 31549753 = 31550132
541 + 31549591 = 31550132
571 + 31549561 = 31550132

Showing the first eight; more decompositions exist.
