Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483882, here are decompositions:

5 + 31483877 = 31483882
11 + 31483871 = 31483882
41 + 31483841 = 31483882
83 + 31483799 = 31483882
149 + 31483733 = 31483882
191 + 31483691 = 31483882
233 + 31483649 = 31483882
389 + 31483493 = 31483882

Showing the first eight; more decompositions exist.
