Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718774, here are decompositions:

17 + 8718757 = 8718774
37 + 8718737 = 8718774
41 + 8718733 = 8718774
47 + 8718727 = 8718774
101 + 8718673 = 8718774
173 + 8718601 = 8718774
193 + 8718581 = 8718774
271 + 8718503 = 8718774

Showing the first eight; more decompositions exist.
