Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718984, here are decompositions:

11 + 8718973 = 8718984
31 + 8718953 = 8718984
67 + 8718917 = 8718984
97 + 8718887 = 8718984
103 + 8718881 = 8718984
107 + 8718877 = 8718984
151 + 8718833 = 8718984
173 + 8718811 = 8718984

Showing the first eight; more decompositions exist.
