Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83728, here are decompositions:

11 + 83717 = 83728
89 + 83639 = 83728
107 + 83621 = 83728
131 + 83597 = 83728
137 + 83591 = 83728
149 + 83579 = 83728
167 + 83561 = 83728
191 + 83537 = 83728

Showing the first eight; more decompositions exist.
