Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718508, here are decompositions:

5 + 8718503 = 8718508
17 + 8718491 = 8718508
47 + 8718461 = 8718508
89 + 8718419 = 8718508
101 + 8718407 = 8718508
107 + 8718401 = 8718508
131 + 8718377 = 8718508
257 + 8718251 = 8718508

Showing the first eight; more decompositions exist.
