Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600646, here are decompositions:

97 + 31600549 = 31600646
193 + 31600453 = 31600646
199 + 31600447 = 31600646
223 + 31600423 = 31600646
313 + 31600333 = 31600646
367 + 31600279 = 31600646
373 + 31600273 = 31600646
457 + 31600189 = 31600646

Showing the first eight; more decompositions exist.
