Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573184, here are decompositions:

31 + 31573153 = 31573184
61 + 31573123 = 31573184
73 + 31573111 = 31573184
127 + 31573057 = 31573184
157 + 31573027 = 31573184
163 + 31573021 = 31573184
241 + 31572943 = 31573184
283 + 31572901 = 31573184

Showing the first eight; more decompositions exist.
