Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573104, here are decompositions:

11 + 31573093 = 31573104
47 + 31573057 = 31573104
67 + 31573037 = 31573104
83 + 31573021 = 31573104
97 + 31573007 = 31573104
163 + 31572941 = 31573104
223 + 31572881 = 31573104
263 + 31572841 = 31573104

Showing the first eight; more decompositions exist.
