Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748450, here are decompositions:

19 + 8748431 = 8748450
31 + 8748419 = 8748450
37 + 8748413 = 8748450
47 + 8748403 = 8748450
83 + 8748367 = 8748450
89 + 8748361 = 8748450
127 + 8748323 = 8748450
163 + 8748287 = 8748450

Showing the first eight; more decompositions exist.
