Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012556, here are decompositions:

7 + 1012549 = 1012556
37 + 1012519 = 1012556
43 + 1012513 = 1012556
67 + 1012489 = 1012556
109 + 1012447 = 1012556
157 + 1012399 = 1012556
277 + 1012279 = 1012556
367 + 1012189 = 1012556

Showing the first eight; more decompositions exist.
