Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653220, here are decompositions:

13 + 8653207 = 8653220
73 + 8653147 = 8653220
109 + 8653111 = 8653220
127 + 8653093 = 8653220
139 + 8653081 = 8653220
157 + 8653063 = 8653220
223 + 8652997 = 8653220
241 + 8652979 = 8653220

Showing the first eight; more decompositions exist.
