Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617444, here are decompositions:

13 + 31617431 = 31617444
31 + 31617413 = 31617444
37 + 31617407 = 31617444
41 + 31617403 = 31617444
71 + 31617373 = 31617444
73 + 31617371 = 31617444
83 + 31617361 = 31617444
151 + 31617293 = 31617444

Showing the first eight; more decompositions exist.
