Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026842, here are decompositions:

13 + 1026829 = 1026842
31 + 1026811 = 1026842
43 + 1026799 = 1026842
109 + 1026733 = 1026842
163 + 1026679 = 1026842
181 + 1026661 = 1026842
613 + 1026229 = 1026842
643 + 1026199 = 1026842

Showing the first eight; more decompositions exist.
