Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022128, here are decompositions:

5 + 1022123 = 1022128
167 + 1021961 = 1022128
431 + 1021697 = 1022128
467 + 1021661 = 1022128
557 + 1021571 = 1022128
587 + 1021541 = 1022128
641 + 1021487 = 1022128
761 + 1021367 = 1022128

Showing the first eight; more decompositions exist.
