Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7230, here are decompositions:

11 + 7219 = 7230
17 + 7213 = 7230
19 + 7211 = 7230
23 + 7207 = 7230
37 + 7193 = 7230
43 + 7187 = 7230
53 + 7177 = 7230
71 + 7159 = 7230

Showing the first eight; more decompositions exist.
