Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609422, here are decompositions:

29 + 31609393 = 31609422
41 + 31609381 = 31609422
83 + 31609339 = 31609422
191 + 31609231 = 31609422
193 + 31609229 = 31609422
199 + 31609223 = 31609422
233 + 31609189 = 31609422
311 + 31609111 = 31609422

Showing the first eight; more decompositions exist.
