Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618200, here are decompositions:

53 + 8618147 = 8618200
113 + 8618087 = 8618200
137 + 8618063 = 8618200
167 + 8618033 = 8618200
179 + 8618021 = 8618200
251 + 8617949 = 8618200
257 + 8617943 = 8618200
401 + 8617799 = 8618200

Showing the first eight; more decompositions exist.
