Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523214, here are decompositions:

5 + 31523209 = 31523214
7 + 31523207 = 31523214
13 + 31523201 = 31523214
53 + 31523161 = 31523214
71 + 31523143 = 31523214
83 + 31523131 = 31523214
101 + 31523113 = 31523214
103 + 31523111 = 31523214

Showing the first eight; more decompositions exist.
