Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492416, here are decompositions:

13 + 31492403 = 31492416
17 + 31492399 = 31492416
23 + 31492393 = 31492416
47 + 31492369 = 31492416
79 + 31492337 = 31492416
97 + 31492319 = 31492416
139 + 31492277 = 31492416
157 + 31492259 = 31492416

Showing the first eight; more decompositions exist.
