Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619238, here are decompositions:

41 + 8619197 = 8619238
71 + 8619167 = 8619238
107 + 8619131 = 8619238
137 + 8619101 = 8619238
167 + 8619071 = 8619238
179 + 8619059 = 8619238
197 + 8619041 = 8619238
239 + 8618999 = 8619238

Showing the first eight; more decompositions exist.
