Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607148, here are decompositions:

11 + 31607137 = 31607148
47 + 31607101 = 31607148
61 + 31607087 = 31607148
101 + 31607047 = 31607148
109 + 31607039 = 31607148
151 + 31606997 = 31607148
191 + 31606957 = 31607148
197 + 31606951 = 31607148

Showing the first eight; more decompositions exist.
