Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738312, here are decompositions:

13 + 8738299 = 8738312
19 + 8738293 = 8738312
31 + 8738281 = 8738312
73 + 8738239 = 8738312
103 + 8738209 = 8738312
151 + 8738161 = 8738312
211 + 8738101 = 8738312
223 + 8738089 = 8738312

Showing the first eight; more decompositions exist.
