Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492362, here are decompositions:

43 + 31492319 = 31492362
101 + 31492261 = 31492362
103 + 31492259 = 31492362
149 + 31492213 = 31492362
199 + 31492163 = 31492362
269 + 31492093 = 31492362
271 + 31492091 = 31492362
281 + 31492081 = 31492362

Showing the first eight; more decompositions exist.
