Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689480, here are decompositions:

17 + 8689463 = 8689480
29 + 8689451 = 8689480
47 + 8689433 = 8689480
131 + 8689349 = 8689480
179 + 8689301 = 8689480
197 + 8689283 = 8689480
257 + 8689223 = 8689480
263 + 8689217 = 8689480

Showing the first eight; more decompositions exist.
