Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15222, here are decompositions:

5 + 15217 = 15222
23 + 15199 = 15222
29 + 15193 = 15222
61 + 15161 = 15222
73 + 15149 = 15222
83 + 15139 = 15222
101 + 15121 = 15222
131 + 15091 = 15222

Showing the first eight; more decompositions exist.
