Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483998, here are decompositions:

17 + 31483981 = 31483998
19 + 31483979 = 31483998
41 + 31483957 = 31483998
71 + 31483927 = 31483998
79 + 31483919 = 31483998
109 + 31483889 = 31483998
127 + 31483871 = 31483998
137 + 31483861 = 31483998

Showing the first eight; more decompositions exist.
