Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573152, here are decompositions:

19 + 31573133 = 31573152
29 + 31573123 = 31573152
41 + 31573111 = 31573152
43 + 31573109 = 31573152
59 + 31573093 = 31573152
131 + 31573021 = 31573152
173 + 31572979 = 31573152
181 + 31572971 = 31573152

Showing the first eight; more decompositions exist.
