Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618424, here are decompositions:

11 + 8618413 = 8618424
37 + 8618387 = 8618424
47 + 8618377 = 8618424
97 + 8618327 = 8618424
107 + 8618317 = 8618424
127 + 8618297 = 8618424
131 + 8618293 = 8618424
137 + 8618287 = 8618424

Showing the first eight; more decompositions exist.
