Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718624, here are decompositions:

23 + 8718601 = 8718624
43 + 8718581 = 8718624
53 + 8718571 = 8718624
137 + 8718487 = 8718624
163 + 8718461 = 8718624
193 + 8718431 = 8718624
197 + 8718427 = 8718624
223 + 8718401 = 8718624

Showing the first eight; more decompositions exist.
