Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7222, here are decompositions:

3 + 7219 = 7222
11 + 7211 = 7222
29 + 7193 = 7222
71 + 7151 = 7222
101 + 7121 = 7222
113 + 7109 = 7222
179 + 7043 = 7222
239 + 6983 = 7222

Showing the first eight; more decompositions exist.
