Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610268, here are decompositions:

31 + 31610237 = 31610268
37 + 31610231 = 31610268
71 + 31610197 = 31610268
97 + 31610171 = 31610268
127 + 31610141 = 31610268
229 + 31610039 = 31610268
257 + 31610011 = 31610268
311 + 31609957 = 31610268

Showing the first eight; more decompositions exist.
