Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465214, here are decompositions:

31 + 31465183 = 31465214
37 + 31465177 = 31465214
61 + 31465153 = 31465214
103 + 31465111 = 31465214
181 + 31465033 = 31465214
211 + 31465003 = 31465214
223 + 31464991 = 31465214
241 + 31464973 = 31465214

Showing the first eight; more decompositions exist.
