Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642316, here are decompositions:

13 + 8642303 = 8642316
79 + 8642237 = 8642316
127 + 8642189 = 8642316
157 + 8642159 = 8642316
197 + 8642119 = 8642316
239 + 8642077 = 8642316
257 + 8642059 = 8642316
283 + 8642033 = 8642316

Showing the first eight; more decompositions exist.
