Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718786, here are decompositions:

7 + 8718779 = 8718786
29 + 8718757 = 8718786
53 + 8718733 = 8718786
59 + 8718727 = 8718786
113 + 8718673 = 8718786
137 + 8718649 = 8718786
283 + 8718503 = 8718786
317 + 8718469 = 8718786

Showing the first eight; more decompositions exist.
