Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12220, here are decompositions:

17 + 12203 = 12220
23 + 12197 = 12220
59 + 12161 = 12220
71 + 12149 = 12220
101 + 12119 = 12220
107 + 12113 = 12220
113 + 12107 = 12220
149 + 12071 = 12220

Showing the first eight; more decompositions exist.
