Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463982, here are decompositions:

19 + 31463963 = 31463982
23 + 31463959 = 31463982
41 + 31463941 = 31463982
61 + 31463921 = 31463982
71 + 31463911 = 31463982
73 + 31463909 = 31463982
89 + 31463893 = 31463982
103 + 31463879 = 31463982

Showing the first eight; more decompositions exist.
