Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045556, here are decompositions:

7 + 1045549 = 1045556
13 + 1045543 = 1045556
163 + 1045393 = 1045556
283 + 1045273 = 1045556
373 + 1045183 = 1045556
433 + 1045123 = 1045556
439 + 1045117 = 1045556
709 + 1044847 = 1045556

Showing the first eight; more decompositions exist.
