Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618444, here are decompositions:

31 + 8618413 = 8618444
67 + 8618377 = 8618444
127 + 8618317 = 8618444
151 + 8618293 = 8618444
157 + 8618287 = 8618444
193 + 8618251 = 8618444
223 + 8618221 = 8618444
271 + 8618173 = 8618444

Showing the first eight; more decompositions exist.
