Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628738, here are decompositions:

11 + 8628727 = 8628738
29 + 8628709 = 8628738
61 + 8628677 = 8628738
109 + 8628629 = 8628738
137 + 8628601 = 8628738
191 + 8628547 = 8628738
257 + 8628481 = 8628738
317 + 8628421 = 8628738

Showing the first eight; more decompositions exist.
