Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689418, here are decompositions:

19 + 8689399 = 8689418
97 + 8689321 = 8689418
109 + 8689309 = 8689418
139 + 8689279 = 8689418
277 + 8689141 = 8689418
307 + 8689111 = 8689418
349 + 8689069 = 8689418
379 + 8689039 = 8689418

Showing the first eight; more decompositions exist.
