Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617576, here are decompositions:

13 + 31617563 = 31617576
17 + 31617559 = 31617576
43 + 31617533 = 31617576
47 + 31617529 = 31617576
73 + 31617503 = 31617576
79 + 31617497 = 31617576
83 + 31617493 = 31617576
127 + 31617449 = 31617576

Showing the first eight; more decompositions exist.
