Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738418, here are decompositions:

11 + 8738407 = 8738418
19 + 8738399 = 8738418
41 + 8738377 = 8738418
67 + 8738351 = 8738418
79 + 8738339 = 8738418
137 + 8738281 = 8738418
179 + 8738239 = 8738418
191 + 8738227 = 8738418

Showing the first eight; more decompositions exist.
