Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617630, here are decompositions:

3 + 8617627 = 8617630
83 + 8617547 = 8617630
107 + 8617523 = 8617630
191 + 8617439 = 8617630
233 + 8617397 = 8617630
239 + 8617391 = 8617630
257 + 8617373 = 8617630
269 + 8617361 = 8617630

Showing the first eight; more decompositions exist.
