Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573116, here are decompositions:

5 + 31573111 = 31573116
7 + 31573109 = 31573116
13 + 31573103 = 31573116
23 + 31573093 = 31573116
59 + 31573057 = 31573116
79 + 31573037 = 31573116
89 + 31573027 = 31573116
109 + 31573007 = 31573116

Showing the first eight; more decompositions exist.
