Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492348, here are decompositions:

11 + 31492337 = 31492348
29 + 31492319 = 31492348
71 + 31492277 = 31492348
89 + 31492259 = 31492348
191 + 31492157 = 31492348
257 + 31492091 = 31492348
269 + 31492079 = 31492348
281 + 31492067 = 31492348

Showing the first eight; more decompositions exist.
