Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638246, here are decompositions:

5 + 8638241 = 8638246
17 + 8638229 = 8638246
47 + 8638199 = 8638246
59 + 8638187 = 8638246
107 + 8638139 = 8638246
179 + 8638067 = 8638246
293 + 8637953 = 8638246
317 + 8637929 = 8638246

Showing the first eight; more decompositions exist.
