Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039220, here are decompositions:

67 + 1039153 = 1039220
109 + 1039111 = 1039220
139 + 1039081 = 1039220
151 + 1039069 = 1039220
181 + 1039039 = 1039220
199 + 1039021 = 1039220
283 + 1038937 = 1039220
307 + 1038913 = 1039220

Showing the first eight; more decompositions exist.
