Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689520, here are decompositions:

31 + 8689489 = 8689520
67 + 8689453 = 8689520
199 + 8689321 = 8689520
211 + 8689309 = 8689520
241 + 8689279 = 8689520
271 + 8689249 = 8689520
277 + 8689243 = 8689520
379 + 8689141 = 8689520

Showing the first eight; more decompositions exist.
