Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045218, here are decompositions:

19 + 1045199 = 1045218
61 + 1045157 = 1045218
67 + 1045151 = 1045218
89 + 1045129 = 1045218
101 + 1045117 = 1045218
107 + 1045111 = 1045218
137 + 1045081 = 1045218
157 + 1045061 = 1045218

Showing the first eight; more decompositions exist.
