Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492474, here are decompositions:

3 + 31492471 = 31492474
53 + 31492421 = 31492474
71 + 31492403 = 31492474
137 + 31492337 = 31492474
197 + 31492277 = 31492474
311 + 31492163 = 31492474
317 + 31492157 = 31492474
383 + 31492091 = 31492474

Showing the first eight; more decompositions exist.
