Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028772, here are decompositions:

11 + 1028761 = 1028772
23 + 1028749 = 1028772
89 + 1028683 = 1028772
103 + 1028669 = 1028772
109 + 1028663 = 1028772
191 + 1028581 = 1028772
193 + 1028579 = 1028772
211 + 1028561 = 1028772

Showing the first eight; more decompositions exist.
