Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031556, here are decompositions:

7 + 1031549 = 1031556
23 + 1031533 = 1031556
67 + 1031489 = 1031556
73 + 1031483 = 1031556
79 + 1031477 = 1031556
109 + 1031447 = 1031556
157 + 1031399 = 1031556
199 + 1031357 = 1031556

Showing the first eight; more decompositions exist.
