Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628408, here are decompositions:

31 + 8628377 = 8628408
59 + 8628349 = 8628408
137 + 8628271 = 8628408
227 + 8628181 = 8628408
251 + 8628157 = 8628408
277 + 8628131 = 8628408
311 + 8628097 = 8628408
331 + 8628077 = 8628408

Showing the first eight; more decompositions exist.
