Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483986, here are decompositions:

5 + 31483981 = 31483986
7 + 31483979 = 31483986
29 + 31483957 = 31483986
59 + 31483927 = 31483986
67 + 31483919 = 31483986
73 + 31483913 = 31483986
97 + 31483889 = 31483986
103 + 31483883 = 31483986

Showing the first eight; more decompositions exist.
