Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031120, here are decompositions:

3 + 1031117 = 1031120
67 + 1031053 = 1031120
73 + 1031047 = 1031120
127 + 1030993 = 1031120
163 + 1030957 = 1031120
379 + 1030741 = 1031120
397 + 1030723 = 1031120
439 + 1030681 = 1031120

Showing the first eight; more decompositions exist.
