Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718244, here are decompositions:

23 + 8718221 = 8718244
47 + 8718197 = 8718244
53 + 8718191 = 8718244
131 + 8718113 = 8718244
233 + 8718011 = 8718244
251 + 8717993 = 8718244
257 + 8717987 = 8718244
263 + 8717981 = 8718244

Showing the first eight; more decompositions exist.
