Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618436, here are decompositions:

7 + 8618429 = 8618436
23 + 8618413 = 8618436
59 + 8618377 = 8618436
97 + 8618339 = 8618436
107 + 8618329 = 8618436
109 + 8618327 = 8618436
139 + 8618297 = 8618436
149 + 8618287 = 8618436

Showing the first eight; more decompositions exist.
