Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689448, here are decompositions:

127 + 8689321 = 8689448
139 + 8689309 = 8689448
199 + 8689249 = 8689448
307 + 8689141 = 8689448
337 + 8689111 = 8689448
379 + 8689069 = 8689448
409 + 8689039 = 8689448
457 + 8688991 = 8689448

Showing the first eight; more decompositions exist.
