Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718278, here are decompositions:

7 + 8718271 = 8718278
31 + 8718247 = 8718278
61 + 8718217 = 8718278
181 + 8718097 = 8718278
271 + 8718007 = 8718278
397 + 8717881 = 8718278
409 + 8717869 = 8718278
421 + 8717857 = 8718278

Showing the first eight; more decompositions exist.
