Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597778, here are decompositions:

19 + 8597759 = 8597778
41 + 8597737 = 8597778
71 + 8597707 = 8597778
109 + 8597669 = 8597778
127 + 8597651 = 8597778
131 + 8597647 = 8597778
139 + 8597639 = 8597778
149 + 8597629 = 8597778

Showing the first eight; more decompositions exist.
