Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550048, here are decompositions:

67 + 31549981 = 31550048
151 + 31549897 = 31550048
157 + 31549891 = 31550048
331 + 31549717 = 31550048
457 + 31549591 = 31550048
487 + 31549561 = 31550048
709 + 31549339 = 31550048
811 + 31549237 = 31550048

Showing the first eight; more decompositions exist.
