Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638848, here are decompositions:

5 + 8638843 = 8638848
41 + 8638807 = 8638848
151 + 8638697 = 8638848
157 + 8638691 = 8638848
227 + 8638621 = 8638848
331 + 8638517 = 8638848
367 + 8638481 = 8638848
397 + 8638451 = 8638848

Showing the first eight; more decompositions exist.
