Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647290, here are decompositions:

13 + 8647277 = 8647290
17 + 8647273 = 8647290
37 + 8647253 = 8647290
59 + 8647231 = 8647290
61 + 8647229 = 8647290
97 + 8647193 = 8647290
107 + 8647183 = 8647290
109 + 8647181 = 8647290

Showing the first eight; more decompositions exist.
