Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738340, here are decompositions:

7 + 8738333 = 8738340
41 + 8738299 = 8738340
47 + 8738293 = 8738340
59 + 8738281 = 8738340
67 + 8738273 = 8738340
101 + 8738239 = 8738340
109 + 8738231 = 8738340
113 + 8738227 = 8738340

Showing the first eight; more decompositions exist.
