Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67646, here are decompositions:

67 + 67579 = 67646
79 + 67567 = 67646
109 + 67537 = 67646
157 + 67489 = 67646
193 + 67453 = 67646
199 + 67447 = 67646
277 + 67369 = 67646
307 + 67339 = 67646

Showing the first eight; more decompositions exist.
