Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77270, here are decompositions:

3 + 77267 = 77270
7 + 77263 = 77270
31 + 77239 = 77270
79 + 77191 = 77270
103 + 77167 = 77270
223 + 77047 = 77270
229 + 77041 = 77270
241 + 77029 = 77270

Showing the first eight; more decompositions exist.
