Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738480, here are decompositions:

7 + 8738473 = 8738480
31 + 8738449 = 8738480
43 + 8738437 = 8738480
73 + 8738407 = 8738480
97 + 8738383 = 8738480
103 + 8738377 = 8738480
181 + 8738299 = 8738480
199 + 8738281 = 8738480

Showing the first eight; more decompositions exist.
