Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718998, here are decompositions:

139 + 8718859 = 8718998
199 + 8718799 = 8718998
241 + 8718757 = 8718998
271 + 8718727 = 8718998
349 + 8718649 = 8718998
397 + 8718601 = 8718998
571 + 8718427 = 8718998
727 + 8718271 = 8718998

Showing the first eight; more decompositions exist.
