Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3222, here are decompositions:

5 + 3217 = 3222
13 + 3209 = 3222
19 + 3203 = 3222
31 + 3191 = 3222
41 + 3181 = 3222
53 + 3169 = 3222
59 + 3163 = 3222
101 + 3121 = 3222

Showing the first eight; more decompositions exist.
