Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601398, here are decompositions:

7 + 8601391 = 8601398
37 + 8601361 = 8601398
67 + 8601331 = 8601398
109 + 8601289 = 8601398
229 + 8601169 = 8601398
241 + 8601157 = 8601398
277 + 8601121 = 8601398
439 + 8600959 = 8601398

Showing the first eight; more decompositions exist.
