Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646538, here are decompositions:

41 + 8646497 = 8646538
59 + 8646479 = 8646538
137 + 8646401 = 8646538
149 + 8646389 = 8646538
239 + 8646299 = 8646538
269 + 8646269 = 8646538
281 + 8646257 = 8646538
311 + 8646227 = 8646538

Showing the first eight; more decompositions exist.
