Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025828, here are decompositions:

61 + 1025767 = 1025828
79 + 1025749 = 1025828
277 + 1025551 = 1025828
409 + 1025419 = 1025828
421 + 1025407 = 1025828
547 + 1025281 = 1025828
571 + 1025257 = 1025828
619 + 1025209 = 1025828

Showing the first eight; more decompositions exist.
