Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13238, here are decompositions:

19 + 13219 = 13238
61 + 13177 = 13238
67 + 13171 = 13238
79 + 13159 = 13238
139 + 13099 = 13238
229 + 13009 = 13238
271 + 12967 = 13238
331 + 12907 = 13238

Showing the first eight; more decompositions exist.
