Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492354, here are decompositions:

17 + 31492337 = 31492354
191 + 31492163 = 31492354
197 + 31492157 = 31492354
263 + 31492091 = 31492354
281 + 31492073 = 31492354
293 + 31492061 = 31492354
461 + 31491893 = 31492354
563 + 31491791 = 31492354

Showing the first eight; more decompositions exist.
