Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718890, here are decompositions:

3 + 8718887 = 8718890
13 + 8718877 = 8718890
31 + 8718859 = 8718890
67 + 8718823 = 8718890
79 + 8718811 = 8718890
97 + 8718793 = 8718890
157 + 8718733 = 8718890
163 + 8718727 = 8718890

Showing the first eight; more decompositions exist.
