Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700450, here are decompositions:

19 + 8700431 = 8700450
29 + 8700421 = 8700450
43 + 8700407 = 8700450
67 + 8700383 = 8700450
89 + 8700361 = 8700450
97 + 8700353 = 8700450
151 + 8700299 = 8700450
163 + 8700287 = 8700450

Showing the first eight; more decompositions exist.
