Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021088, here are decompositions:

7 + 1021081 = 1021088
97 + 1020991 = 1021088
109 + 1020979 = 1021088
127 + 1020961 = 1021088
157 + 1020931 = 1021088
181 + 1020907 = 1021088
241 + 1020847 = 1021088
331 + 1020757 = 1021088

Showing the first eight; more decompositions exist.
