Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550362, here are decompositions:

5 + 31550357 = 31550362
23 + 31550339 = 31550362
149 + 31550213 = 31550362
251 + 31550111 = 31550362
269 + 31550093 = 31550362
383 + 31549979 = 31550362
443 + 31549919 = 31550362
563 + 31549799 = 31550362

Showing the first eight; more decompositions exist.
