Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048742, here are decompositions:

61 + 1048681 = 1048742
109 + 1048633 = 1048742
193 + 1048549 = 1048742
433 + 1048309 = 1048742
523 + 1048219 = 1048742
613 + 1048129 = 1048742
619 + 1048123 = 1048742
691 + 1048051 = 1048742

Showing the first eight; more decompositions exist.
