Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718506, here are decompositions:

3 + 8718503 = 8718506
19 + 8718487 = 8718506
37 + 8718469 = 8718506
67 + 8718439 = 8718506
79 + 8718427 = 8718506
157 + 8718349 = 8718506
163 + 8718343 = 8718506
193 + 8718313 = 8718506

Showing the first eight; more decompositions exist.
