Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619268, here are decompositions:

5 + 8619263 = 8619268
71 + 8619197 = 8619268
101 + 8619167 = 8619268
137 + 8619131 = 8619268
167 + 8619101 = 8619268
191 + 8619077 = 8619268
197 + 8619071 = 8619268
227 + 8619041 = 8619268

Showing the first eight; more decompositions exist.
