Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610536, here are decompositions:

17 + 31610519 = 31610536
173 + 31610363 = 31610536
197 + 31610339 = 31610536
257 + 31610279 = 31610536
443 + 31610093 = 31610536
563 + 31609973 = 31610536
569 + 31609967 = 31610536
599 + 31609937 = 31610536

Showing the first eight; more decompositions exist.
