Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028120, here are decompositions:

3 + 1028117 = 1028120
7 + 1028113 = 1028120
13 + 1028107 = 1028120
19 + 1028101 = 1028120
31 + 1028089 = 1028120
73 + 1028047 = 1028120
97 + 1028023 = 1028120
103 + 1028017 = 1028120

Showing the first eight; more decompositions exist.
