Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609416, here are decompositions:

23 + 31609393 = 31609416
127 + 31609289 = 31609416
149 + 31609267 = 31609416
193 + 31609223 = 31609416
227 + 31609189 = 31609416
337 + 31609079 = 31609416
367 + 31609049 = 31609416
383 + 31609033 = 31609416

Showing the first eight; more decompositions exist.
