Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718630, here are decompositions:

29 + 8718601 = 8718630
59 + 8718571 = 8718630
127 + 8718503 = 8718630
139 + 8718491 = 8718630
191 + 8718439 = 8718630
199 + 8718431 = 8718630
211 + 8718419 = 8718630
223 + 8718407 = 8718630

Showing the first eight; more decompositions exist.
