Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718938, here are decompositions:

31 + 8718907 = 8718938
61 + 8718877 = 8718938
79 + 8718859 = 8718938
127 + 8718811 = 8718938
139 + 8718799 = 8718938
181 + 8718757 = 8718938
211 + 8718727 = 8718938
229 + 8718709 = 8718938

Showing the first eight; more decompositions exist.
