Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709450, here are decompositions:

7 + 8709443 = 8709450
19 + 8709431 = 8709450
67 + 8709383 = 8709450
73 + 8709377 = 8709450
89 + 8709361 = 8709450
137 + 8709313 = 8709450
149 + 8709301 = 8709450
151 + 8709299 = 8709450

Showing the first eight; more decompositions exist.
