Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7218, here are decompositions:

5 + 7213 = 7218
7 + 7211 = 7218
11 + 7207 = 7218
31 + 7187 = 7218
41 + 7177 = 7218
59 + 7159 = 7218
67 + 7151 = 7218
89 + 7129 = 7218

Showing the first eight; more decompositions exist.
