Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492332, here are decompositions:

13 + 31492319 = 31492332
71 + 31492261 = 31492332
73 + 31492259 = 31492332
89 + 31492243 = 31492332
239 + 31492093 = 31492332
241 + 31492091 = 31492332
251 + 31492081 = 31492332
271 + 31492061 = 31492332

Showing the first eight; more decompositions exist.
