Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617504, here are decompositions:

7 + 31617497 = 31617504
11 + 31617493 = 31617504
43 + 31617461 = 31617504
47 + 31617457 = 31617504
73 + 31617431 = 31617504
97 + 31617407 = 31617504
101 + 31617403 = 31617504
131 + 31617373 = 31617504

Showing the first eight; more decompositions exist.
