Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618450, here are decompositions:

7 + 8618443 = 8618450
37 + 8618413 = 8618450
73 + 8618377 = 8618450
157 + 8618293 = 8618450
163 + 8618287 = 8618450
193 + 8618257 = 8618450
199 + 8618251 = 8618450
229 + 8618221 = 8618450

Showing the first eight; more decompositions exist.
