Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15212, here are decompositions:

13 + 15199 = 15212
19 + 15193 = 15212
73 + 15139 = 15212
139 + 15073 = 15212
151 + 15061 = 15212
181 + 15031 = 15212
199 + 15013 = 15212
229 + 14983 = 15212

Showing the first eight; more decompositions exist.
