Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51222, here are decompositions:

5 + 51217 = 51222
19 + 51203 = 51222
23 + 51199 = 51222
29 + 51193 = 51222
53 + 51169 = 51222
71 + 51151 = 51222
89 + 51133 = 51222
113 + 51109 = 51222

Showing the first eight; more decompositions exist.
