Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718330, here are decompositions:

17 + 8718313 = 8718330
29 + 8718301 = 8718330
53 + 8718277 = 8718330
59 + 8718271 = 8718330
79 + 8718251 = 8718330
83 + 8718247 = 8718330
109 + 8718221 = 8718330
113 + 8718217 = 8718330

Showing the first eight; more decompositions exist.
