Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618204, here are decompositions:

31 + 8618173 = 8618204
73 + 8618131 = 8618204
97 + 8618107 = 8618204
157 + 8618047 = 8618204
163 + 8618041 = 8618204
211 + 8617993 = 8618204
271 + 8617933 = 8618204
277 + 8617927 = 8618204

Showing the first eight; more decompositions exist.
