Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718940, here are decompositions:

23 + 8718917 = 8718940
53 + 8718887 = 8718940
59 + 8718881 = 8718940
71 + 8718869 = 8718940
89 + 8718851 = 8718940
101 + 8718839 = 8718940
107 + 8718833 = 8718940
137 + 8718803 = 8718940

Showing the first eight; more decompositions exist.
