Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025790, here are decompositions:

23 + 1025767 = 1025790
41 + 1025749 = 1025790
43 + 1025747 = 1025790
83 + 1025707 = 1025790
97 + 1025693 = 1025790
131 + 1025659 = 1025790
137 + 1025653 = 1025790
149 + 1025641 = 1025790

Showing the first eight; more decompositions exist.
