Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025622, here are decompositions:

11 + 1025611 = 1025622
43 + 1025579 = 1025622
61 + 1025561 = 1025622
71 + 1025551 = 1025622
79 + 1025543 = 1025622
109 + 1025513 = 1025622
113 + 1025509 = 1025622
139 + 1025483 = 1025622

Showing the first eight; more decompositions exist.
