Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483960, here are decompositions:

3 + 31483957 = 31483960
41 + 31483919 = 31483960
47 + 31483913 = 31483960
71 + 31483889 = 31483960
83 + 31483877 = 31483960
89 + 31483871 = 31483960
227 + 31483733 = 31483960
269 + 31483691 = 31483960

Showing the first eight; more decompositions exist.
