Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042560, here are decompositions:

31 + 1042529 = 1042560
37 + 1042523 = 1042560
41 + 1042519 = 1042560
73 + 1042487 = 1042560
109 + 1042451 = 1042560
179 + 1042381 = 1042560
191 + 1042369 = 1042560
227 + 1042333 = 1042560

Showing the first eight; more decompositions exist.
