Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492274, here are decompositions:

13 + 31492261 = 31492274
31 + 31492243 = 31492274
61 + 31492213 = 31492274
181 + 31492093 = 31492274
193 + 31492081 = 31492274
223 + 31492051 = 31492274
241 + 31492033 = 31492274
433 + 31491841 = 31492274

Showing the first eight; more decompositions exist.
