Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7216, here are decompositions:

3 + 7213 = 7216
5 + 7211 = 7216
23 + 7193 = 7216
29 + 7187 = 7216
89 + 7127 = 7216
107 + 7109 = 7216
113 + 7103 = 7216
137 + 7079 = 7216

Showing the first eight; more decompositions exist.
