Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574010, here are decompositions:

11 + 31573999 = 31574010
43 + 31573967 = 31574010
53 + 31573957 = 31574010
79 + 31573931 = 31574010
151 + 31573859 = 31574010
157 + 31573853 = 31574010
163 + 31573847 = 31574010
179 + 31573831 = 31574010

Showing the first eight; more decompositions exist.
