Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573044, here are decompositions:

7 + 31573037 = 31573044
17 + 31573027 = 31573044
23 + 31573021 = 31573044
37 + 31573007 = 31573044
73 + 31572971 = 31573044
101 + 31572943 = 31573044
103 + 31572941 = 31573044
163 + 31572881 = 31573044

Showing the first eight; more decompositions exist.
