Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82728, here are decompositions:

5 + 82723 = 82728
7 + 82721 = 82728
29 + 82699 = 82728
71 + 82657 = 82728
109 + 82619 = 82728
127 + 82601 = 82728
137 + 82591 = 82728
157 + 82571 = 82728

Showing the first eight; more decompositions exist.
