Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483912, here are decompositions:

23 + 31483889 = 31483912
29 + 31483883 = 31483912
41 + 31483871 = 31483912
71 + 31483841 = 31483912
113 + 31483799 = 31483912
179 + 31483733 = 31483912
263 + 31483649 = 31483912
359 + 31483553 = 31483912

Showing the first eight; more decompositions exist.
