Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573050, here are decompositions:

13 + 31573037 = 31573050
23 + 31573027 = 31573050
29 + 31573021 = 31573050
43 + 31573007 = 31573050
71 + 31572979 = 31573050
79 + 31572971 = 31573050
101 + 31572949 = 31573050
107 + 31572943 = 31573050

Showing the first eight; more decompositions exist.
