Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619448, here are decompositions:

11 + 8619437 = 8619448
17 + 8619431 = 8619448
179 + 8619269 = 8619448
251 + 8619197 = 8619448
281 + 8619167 = 8619448
317 + 8619131 = 8619448
347 + 8619101 = 8619448
389 + 8619059 = 8619448

Showing the first eight; more decompositions exist.
