Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738390, here are decompositions:

7 + 8738383 = 8738390
13 + 8738377 = 8738390
97 + 8738293 = 8738390
109 + 8738281 = 8738390
127 + 8738263 = 8738390
151 + 8738239 = 8738390
163 + 8738227 = 8738390
181 + 8738209 = 8738390

Showing the first eight; more decompositions exist.
