Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609410, here are decompositions:

17 + 31609393 = 31609410
29 + 31609381 = 31609410
71 + 31609339 = 31609410
179 + 31609231 = 31609410
181 + 31609229 = 31609410
197 + 31609213 = 31609410
293 + 31609117 = 31609410
317 + 31609093 = 31609410

Showing the first eight; more decompositions exist.
