Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7226, here are decompositions:

7 + 7219 = 7226
13 + 7213 = 7226
19 + 7207 = 7226
67 + 7159 = 7226
97 + 7129 = 7226
157 + 7069 = 7226
199 + 7027 = 7226
229 + 6997 = 7226

Showing the first eight; more decompositions exist.
