Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13212, here are decompositions:

29 + 13183 = 13212
41 + 13171 = 13212
53 + 13159 = 13212
61 + 13151 = 13212
103 + 13109 = 13212
109 + 13103 = 13212
113 + 13099 = 13212
149 + 13063 = 13212

Showing the first eight; more decompositions exist.
