Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10646, here are decompositions:

7 + 10639 = 10646
19 + 10627 = 10646
79 + 10567 = 10646
193 + 10453 = 10646
277 + 10369 = 10646
313 + 10333 = 10646
373 + 10273 = 10646
379 + 10267 = 10646

Showing the first eight; more decompositions exist.
