Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7214, here are decompositions:

3 + 7211 = 7214
7 + 7207 = 7214
37 + 7177 = 7214
157 + 7057 = 7214
223 + 6991 = 7214
307 + 6907 = 7214
331 + 6883 = 7214
373 + 6841 = 7214

Showing the first eight; more decompositions exist.
