Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025798, here are decompositions:

31 + 1025767 = 1025798
139 + 1025659 = 1025798
157 + 1025641 = 1025798
379 + 1025419 = 1025798
541 + 1025257 = 1025798
601 + 1025197 = 1025798
661 + 1025137 = 1025798
751 + 1025047 = 1025798

Showing the first eight; more decompositions exist.
