Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109728, here are decompositions:

7 + 109721 = 109728
11 + 109717 = 109728
67 + 109661 = 109728
89 + 109639 = 109728
107 + 109621 = 109728
109 + 109619 = 109728
131 + 109597 = 109728
139 + 109589 = 109728

Showing the first eight; more decompositions exist.
