Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492338, here are decompositions:

19 + 31492319 = 31492338
61 + 31492277 = 31492338
79 + 31492259 = 31492338
181 + 31492157 = 31492338
257 + 31492081 = 31492338
271 + 31492067 = 31492338
277 + 31492061 = 31492338
307 + 31492031 = 31492338

Showing the first eight; more decompositions exist.
