Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483988, here are decompositions:

7 + 31483981 = 31483988
31 + 31483957 = 31483988
61 + 31483927 = 31483988
127 + 31483861 = 31483988
181 + 31483807 = 31483988
199 + 31483789 = 31483988
229 + 31483759 = 31483988
439 + 31483549 = 31483988

Showing the first eight; more decompositions exist.
