Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67728, here are decompositions:

5 + 67723 = 67728
19 + 67709 = 67728
29 + 67699 = 67728
97 + 67631 = 67728
109 + 67619 = 67728
127 + 67601 = 67728
139 + 67589 = 67728
149 + 67579 = 67728

Showing the first eight; more decompositions exist.
