Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492356, here are decompositions:

19 + 31492337 = 31492356
37 + 31492319 = 31492356
79 + 31492277 = 31492356
97 + 31492259 = 31492356
113 + 31492243 = 31492356
193 + 31492163 = 31492356
199 + 31492157 = 31492356
263 + 31492093 = 31492356

Showing the first eight; more decompositions exist.
