Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637798, here are decompositions:

7 + 8637791 = 8637798
11 + 8637787 = 8637798
19 + 8637779 = 8637798
97 + 8637701 = 8637798
101 + 8637697 = 8637798
131 + 8637667 = 8637798
157 + 8637641 = 8637798
179 + 8637619 = 8637798

Showing the first eight; more decompositions exist.
