Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025556, here are decompositions:

5 + 1025551 = 1025556
13 + 1025543 = 1025556
19 + 1025537 = 1025556
43 + 1025513 = 1025556
47 + 1025509 = 1025556
53 + 1025503 = 1025556
73 + 1025483 = 1025556
79 + 1025477 = 1025556

Showing the first eight; more decompositions exist.
