Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573064, here are decompositions:

7 + 31573057 = 31573064
37 + 31573027 = 31573064
43 + 31573021 = 31573064
163 + 31572901 = 31573064
223 + 31572841 = 31573064
241 + 31572823 = 31573064
331 + 31572733 = 31573064
337 + 31572727 = 31573064

Showing the first eight; more decompositions exist.
