Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718740, here are decompositions:

3 + 8718737 = 8718740
7 + 8718733 = 8718740
13 + 8718727 = 8718740
31 + 8718709 = 8718740
67 + 8718673 = 8718740
139 + 8718601 = 8718740
271 + 8718469 = 8718740
313 + 8718427 = 8718740

Showing the first eight; more decompositions exist.
