Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619378, here are decompositions:

109 + 8619269 = 8619378
137 + 8619241 = 8619378
149 + 8619229 = 8619378
167 + 8619211 = 8619378
179 + 8619199 = 8619378
181 + 8619197 = 8619378
211 + 8619167 = 8619378
227 + 8619151 = 8619378

Showing the first eight; more decompositions exist.
