Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647194, here are decompositions:

11 + 8647183 = 8647194
13 + 8647181 = 8647194
37 + 8647157 = 8647194
67 + 8647127 = 8647194
71 + 8647123 = 8647194
103 + 8647091 = 8647194
131 + 8647063 = 8647194
151 + 8647043 = 8647194

Showing the first eight; more decompositions exist.
