Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597918, here are decompositions:

61 + 8597857 = 8597918
79 + 8597839 = 8597918
97 + 8597821 = 8597918
181 + 8597737 = 8597918
211 + 8597707 = 8597918
271 + 8597647 = 8597918
331 + 8597587 = 8597918
367 + 8597551 = 8597918

Showing the first eight; more decompositions exist.
