Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012790, here are decompositions:

19 + 1012771 = 1012790
73 + 1012717 = 1012790
127 + 1012663 = 1012790
157 + 1012633 = 1012790
193 + 1012597 = 1012790
199 + 1012591 = 1012790
241 + 1012549 = 1012790
271 + 1012519 = 1012790

Showing the first eight; more decompositions exist.
