Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020428, here are decompositions:

67 + 1020361 = 1020428
127 + 1020301 = 1020428
181 + 1020247 = 1020428
271 + 1020157 = 1020428
349 + 1020079 = 1020428
379 + 1020049 = 1020428
421 + 1020007 = 1020428
457 + 1019971 = 1020428

Showing the first eight; more decompositions exist.
