Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718612, here are decompositions:

11 + 8718601 = 8718612
31 + 8718581 = 8718612
41 + 8718571 = 8718612
73 + 8718539 = 8718612
109 + 8718503 = 8718612
151 + 8718461 = 8718612
173 + 8718439 = 8718612
181 + 8718431 = 8718612

Showing the first eight; more decompositions exist.
