Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018224, here are decompositions:

7 + 1018217 = 1018224
17 + 1018207 = 1018224
23 + 1018201 = 1018224
47 + 1018177 = 1018224
101 + 1018123 = 1018224
127 + 1018097 = 1018224
167 + 1018057 = 1018224
227 + 1017997 = 1018224

Showing the first eight; more decompositions exist.
