Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13646, here are decompositions:

13 + 13633 = 13646
19 + 13627 = 13646
79 + 13567 = 13646
109 + 13537 = 13646
229 + 13417 = 13646
307 + 13339 = 13646
337 + 13309 = 13646
349 + 13297 = 13646

Showing the first eight; more decompositions exist.
