Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643316, here are decompositions:

29 + 8643287 = 8643316
107 + 8643209 = 8643316
167 + 8643149 = 8643316
173 + 8643143 = 8643316
179 + 8643137 = 8643316
233 + 8643083 = 8643316
239 + 8643077 = 8643316
257 + 8643059 = 8643316

Showing the first eight; more decompositions exist.
