Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639410, here are decompositions:

29 + 8639381 = 8639410
47 + 8639363 = 8639410
137 + 8639273 = 8639410
149 + 8639261 = 8639410
191 + 8639219 = 8639410
233 + 8639177 = 8639410
239 + 8639171 = 8639410
257 + 8639153 = 8639410

Showing the first eight; more decompositions exist.
