Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718250, here are decompositions:

3 + 8718247 = 8718250
29 + 8718221 = 8718250
53 + 8718197 = 8718250
59 + 8718191 = 8718250
137 + 8718113 = 8718250
239 + 8718011 = 8718250
251 + 8717999 = 8718250
257 + 8717993 = 8718250

Showing the first eight; more decompositions exist.
