Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628200, here are decompositions:

13 + 8628187 = 8628200
19 + 8628181 = 8628200
43 + 8628157 = 8628200
79 + 8628121 = 8628200
103 + 8628097 = 8628200
151 + 8628049 = 8628200
181 + 8628019 = 8628200
193 + 8628007 = 8628200

Showing the first eight; more decompositions exist.
