Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025690, here are decompositions:

31 + 1025659 = 1025690
37 + 1025653 = 1025690
67 + 1025623 = 1025690
79 + 1025611 = 1025690
139 + 1025551 = 1025690
181 + 1025509 = 1025690
271 + 1025419 = 1025690
277 + 1025413 = 1025690

Showing the first eight; more decompositions exist.
