Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450214, here are decompositions:

7 + 31450207 = 31450214
73 + 31450141 = 31450214
97 + 31450117 = 31450214
157 + 31450057 = 31450214
181 + 31450033 = 31450214
193 + 31450021 = 31450214
223 + 31449991 = 31450214
277 + 31449937 = 31450214

Showing the first eight; more decompositions exist.
