Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718818, here are decompositions:

7 + 8718811 = 8718818
19 + 8718799 = 8718818
61 + 8718757 = 8718818
109 + 8718709 = 8718818
331 + 8718487 = 8718818
349 + 8718469 = 8718818
379 + 8718439 = 8718818
541 + 8718277 = 8718818

Showing the first eight; more decompositions exist.
