Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628528, here are decompositions:

47 + 8628481 = 8628528
79 + 8628449 = 8628528
107 + 8628421 = 8628528
151 + 8628377 = 8628528
179 + 8628349 = 8628528
257 + 8628271 = 8628528
347 + 8628181 = 8628528
367 + 8628161 = 8628528

Showing the first eight; more decompositions exist.
