Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738328, here are decompositions:

29 + 8738299 = 8738328
47 + 8738281 = 8738328
89 + 8738239 = 8738328
97 + 8738231 = 8738328
101 + 8738227 = 8738328
127 + 8738201 = 8738328
167 + 8738161 = 8738328
199 + 8738129 = 8738328

Showing the first eight; more decompositions exist.
