Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025646, here are decompositions:

5 + 1025641 = 1025646
23 + 1025623 = 1025646
67 + 1025579 = 1025646
103 + 1025543 = 1025646
109 + 1025537 = 1025646
137 + 1025509 = 1025646
163 + 1025483 = 1025646
227 + 1025419 = 1025646

Showing the first eight; more decompositions exist.
