Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718782, here are decompositions:

3 + 8718779 = 8718782
73 + 8718709 = 8718782
109 + 8718673 = 8718782
181 + 8718601 = 8718782
211 + 8718571 = 8718782
313 + 8718469 = 8718782
433 + 8718349 = 8718782
439 + 8718343 = 8718782

Showing the first eight; more decompositions exist.
