Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016420, here are decompositions:

19 + 1016401 = 1016420
61 + 1016359 = 1016420
79 + 1016341 = 1016420
157 + 1016263 = 1016420
193 + 1016227 = 1016420
199 + 1016221 = 1016420
277 + 1016143 = 1016420
283 + 1016137 = 1016420

Showing the first eight; more decompositions exist.
