Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483608, here are decompositions:

11 + 31483597 = 31483608
31 + 31483577 = 31483608
59 + 31483549 = 31483608
61 + 31483547 = 31483608
137 + 31483471 = 31483608
139 + 31483469 = 31483608
151 + 31483457 = 31483608
179 + 31483429 = 31483608

Showing the first eight; more decompositions exist.
