Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492254, here are decompositions:

11 + 31492243 = 31492254
41 + 31492213 = 31492254
97 + 31492157 = 31492254
163 + 31492091 = 31492254
173 + 31492081 = 31492254
181 + 31492073 = 31492254
193 + 31492061 = 31492254
223 + 31492031 = 31492254

Showing the first eight; more decompositions exist.
