Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049120, here are decompositions:

3 + 1049117 = 1049120
19 + 1049101 = 1049120
31 + 1049089 = 1049120
43 + 1049077 = 1049120
97 + 1049023 = 1049120
109 + 1049011 = 1049120
157 + 1048963 = 1049120
211 + 1048909 = 1049120

Showing the first eight; more decompositions exist.
