Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043628, here are decompositions:

11 + 1043617 = 1043628
29 + 1043599 = 1043628
31 + 1043597 = 1043628
37 + 1043591 = 1043628
41 + 1043587 = 1043628
71 + 1043557 = 1043628
97 + 1043531 = 1043628
107 + 1043521 = 1043628

Showing the first eight; more decompositions exist.
