Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684538, here are decompositions:

17 + 8684521 = 8684538
59 + 8684479 = 8684538
67 + 8684471 = 8684538
101 + 8684437 = 8684538
127 + 8684411 = 8684538
131 + 8684407 = 8684538
179 + 8684359 = 8684538
197 + 8684341 = 8684538

Showing the first eight; more decompositions exist.
