Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492284, here are decompositions:

7 + 31492277 = 31492284
23 + 31492261 = 31492284
41 + 31492243 = 31492284
71 + 31492213 = 31492284
127 + 31492157 = 31492284
191 + 31492093 = 31492284
193 + 31492091 = 31492284
211 + 31492073 = 31492284

Showing the first eight; more decompositions exist.
