Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022772, here are decompositions:

11 + 1022761 = 1022772
43 + 1022729 = 1022772
53 + 1022719 = 1022772
71 + 1022701 = 1022772
83 + 1022689 = 1022772
89 + 1022683 = 1022772
139 + 1022633 = 1022772
181 + 1022591 = 1022772

Showing the first eight; more decompositions exist.
