Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609446, here are decompositions:

53 + 31609393 = 31609446
107 + 31609339 = 31609446
157 + 31609289 = 31609446
179 + 31609267 = 31609446
223 + 31609223 = 31609446
233 + 31609213 = 31609446
257 + 31609189 = 31609446
353 + 31609093 = 31609446

Showing the first eight; more decompositions exist.
