Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683428, here are decompositions:

97 + 8683331 = 8683428
101 + 8683327 = 8683428
107 + 8683321 = 8683428
109 + 8683319 = 8683428
167 + 8683261 = 8683428
179 + 8683249 = 8683428
191 + 8683237 = 8683428
197 + 8683231 = 8683428

Showing the first eight; more decompositions exist.
