Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672436, here are decompositions:

7 + 8672429 = 8672436
13 + 8672423 = 8672436
29 + 8672407 = 8672436
83 + 8672353 = 8672436
89 + 8672347 = 8672436
103 + 8672333 = 8672436
139 + 8672297 = 8672436
163 + 8672273 = 8672436

Showing the first eight; more decompositions exist.
