Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610552, here are decompositions:

13 + 31610539 = 31610552
31 + 31610521 = 31610552
139 + 31610413 = 31610552
163 + 31610389 = 31610552
199 + 31610353 = 31610552
283 + 31610269 = 31610552
409 + 31610143 = 31610552
439 + 31610113 = 31610552

Showing the first eight; more decompositions exist.
