Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483680, here are decompositions:

17 + 31483663 = 31483680
31 + 31483649 = 31483680
83 + 31483597 = 31483680
97 + 31483583 = 31483680
103 + 31483577 = 31483680
127 + 31483553 = 31483680
131 + 31483549 = 31483680
211 + 31483469 = 31483680

Showing the first eight; more decompositions exist.
