Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051790, here are decompositions:

31 + 1051759 = 1051790
43 + 1051747 = 1051790
73 + 1051717 = 1051790
127 + 1051663 = 1051790
151 + 1051639 = 1051790
199 + 1051591 = 1051790
241 + 1051549 = 1051790
283 + 1051507 = 1051790

Showing the first eight; more decompositions exist.
