Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550444, here are decompositions:

7 + 31550437 = 31550444
43 + 31550401 = 31550444
73 + 31550371 = 31550444
157 + 31550287 = 31550444
193 + 31550251 = 31550444
223 + 31550221 = 31550444
307 + 31550137 = 31550444
313 + 31550131 = 31550444

Showing the first eight; more decompositions exist.
