Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550248, here are decompositions:

47 + 31550201 = 31550248
71 + 31550177 = 31550248
137 + 31550111 = 31550248
227 + 31550021 = 31550248
269 + 31549979 = 31550248
281 + 31549967 = 31550248
419 + 31549829 = 31550248
449 + 31549799 = 31550248

Showing the first eight; more decompositions exist.
