Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618480, here are decompositions:

37 + 8618443 = 8618480
67 + 8618413 = 8618480
103 + 8618377 = 8618480
151 + 8618329 = 8618480
163 + 8618317 = 8618480
193 + 8618287 = 8618480
223 + 8618257 = 8618480
229 + 8618251 = 8618480

Showing the first eight; more decompositions exist.
