Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610350, here are decompositions:

11 + 31610339 = 31610350
17 + 31610333 = 31610350
59 + 31610291 = 31610350
71 + 31610279 = 31610350
113 + 31610237 = 31610350
137 + 31610213 = 31610350
179 + 31610171 = 31610350
257 + 31610093 = 31610350

Showing the first eight; more decompositions exist.
