Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617450, here are decompositions:

3 + 8617447 = 8617450
11 + 8617439 = 8617450
53 + 8617397 = 8617450
59 + 8617391 = 8617450
89 + 8617361 = 8617450
131 + 8617319 = 8617450
137 + 8617313 = 8617450
173 + 8617277 = 8617450

Showing the first eight; more decompositions exist.
