Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638348, here are decompositions:

11 + 8638337 = 8638348
29 + 8638319 = 8638348
71 + 8638277 = 8638348
101 + 8638247 = 8638348
107 + 8638241 = 8638348
149 + 8638199 = 8638348
197 + 8638151 = 8638348
227 + 8638121 = 8638348

Showing the first eight; more decompositions exist.
