Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618418, here are decompositions:

5 + 8618413 = 8618418
31 + 8618387 = 8618418
41 + 8618377 = 8618418
79 + 8618339 = 8618418
89 + 8618329 = 8618418
101 + 8618317 = 8618418
131 + 8618287 = 8618418
167 + 8618251 = 8618418

Showing the first eight; more decompositions exist.
