Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025628, here are decompositions:

5 + 1025623 = 1025628
7 + 1025621 = 1025628
17 + 1025611 = 1025628
67 + 1025561 = 1025628
151 + 1025477 = 1025628
211 + 1025417 = 1025628
277 + 1025351 = 1025628
281 + 1025347 = 1025628

Showing the first eight; more decompositions exist.
