Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617382, here are decompositions:

3 + 31617379 = 31617382
11 + 31617371 = 31617382
53 + 31617329 = 31617382
89 + 31617293 = 31617382
101 + 31617281 = 31617382
113 + 31617269 = 31617382
131 + 31617251 = 31617382
233 + 31617149 = 31617382

Showing the first eight; more decompositions exist.
