Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016240, here are decompositions:

3 + 1016237 = 1016240
13 + 1016227 = 1016240
19 + 1016221 = 1016240
37 + 1016203 = 1016240
67 + 1016173 = 1016240
97 + 1016143 = 1016240
103 + 1016137 = 1016240
151 + 1016089 = 1016240

Showing the first eight; more decompositions exist.
