Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610152, here are decompositions:

11 + 31610141 = 31610152
59 + 31610093 = 31610152
71 + 31610081 = 31610152
89 + 31610063 = 31610152
113 + 31610039 = 31610152
179 + 31609973 = 31610152
269 + 31609883 = 31610152
281 + 31609871 = 31610152

Showing the first eight; more decompositions exist.
