Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492422, here are decompositions:

19 + 31492403 = 31492422
23 + 31492399 = 31492422
29 + 31492393 = 31492422
53 + 31492369 = 31492422
103 + 31492319 = 31492422
163 + 31492259 = 31492422
179 + 31492243 = 31492422
331 + 31492091 = 31492422

Showing the first eight; more decompositions exist.
