Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689486, here are decompositions:

5 + 8689481 = 8689486
23 + 8689463 = 8689486
53 + 8689433 = 8689486
137 + 8689349 = 8689486
167 + 8689319 = 8689486
227 + 8689259 = 8689486
263 + 8689223 = 8689486
269 + 8689217 = 8689486

Showing the first eight; more decompositions exist.
