Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77212, here are decompositions:

11 + 77201 = 77212
41 + 77171 = 77212
59 + 77153 = 77212
71 + 77141 = 77212
131 + 77081 = 77212
251 + 76961 = 77212
263 + 76949 = 77212
269 + 76943 = 77212

Showing the first eight; more decompositions exist.
