Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718516, here are decompositions:

13 + 8718503 = 8718516
29 + 8718487 = 8718516
47 + 8718469 = 8718516
89 + 8718427 = 8718516
97 + 8718419 = 8718516
109 + 8718407 = 8718516
139 + 8718377 = 8718516
167 + 8718349 = 8718516

Showing the first eight; more decompositions exist.
