Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492350, here are decompositions:

13 + 31492337 = 31492350
31 + 31492319 = 31492350
73 + 31492277 = 31492350
89 + 31492261 = 31492350
107 + 31492243 = 31492350
137 + 31492213 = 31492350
193 + 31492157 = 31492350
257 + 31492093 = 31492350

Showing the first eight; more decompositions exist.
