Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597820, here are decompositions:

37 + 8597783 = 8597820
61 + 8597759 = 8597820
67 + 8597753 = 8597820
83 + 8597737 = 8597820
97 + 8597723 = 8597820
113 + 8597707 = 8597820
137 + 8597683 = 8597820
151 + 8597669 = 8597820

Showing the first eight; more decompositions exist.
