Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682178, here are decompositions:

137 + 8682041 = 8682178
179 + 8681999 = 8682178
347 + 8681831 = 8682178
389 + 8681789 = 8682178
509 + 8681669 = 8682178
599 + 8681579 = 8682178
809 + 8681369 = 8682178
821 + 8681357 = 8682178

Showing the first eight; more decompositions exist.
