Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463832, here are decompositions:

5 + 31463827 = 31463832
53 + 31463779 = 31463832
73 + 31463759 = 31463832
89 + 31463743 = 31463832
151 + 31463681 = 31463832
241 + 31463591 = 31463832
313 + 31463519 = 31463832
349 + 31463483 = 31463832

Showing the first eight; more decompositions exist.
