Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629398, here are decompositions:

101 + 8629297 = 8629398
157 + 8629241 = 8629398
199 + 8629199 = 8629398
227 + 8629171 = 8629398
229 + 8629169 = 8629398
241 + 8629157 = 8629398
257 + 8629141 = 8629398
311 + 8629087 = 8629398

Showing the first eight; more decompositions exist.
