Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573214, here are decompositions:

3 + 31573211 = 31573214
61 + 31573153 = 31573214
103 + 31573111 = 31573214
157 + 31573057 = 31573214
193 + 31573021 = 31573214
271 + 31572943 = 31573214
313 + 31572901 = 31573214
373 + 31572841 = 31573214

Showing the first eight; more decompositions exist.
