Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655278, here are decompositions:

19 + 8655259 = 8655278
61 + 8655217 = 8655278
67 + 8655211 = 8655278
241 + 8655037 = 8655278
271 + 8655007 = 8655278
337 + 8654941 = 8655278
439 + 8654839 = 8655278
661 + 8654617 = 8655278

Showing the first eight; more decompositions exist.
