Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643406, here are decompositions:

47 + 8643359 = 8643406
89 + 8643317 = 8643406
197 + 8643209 = 8643406
257 + 8643149 = 8643406
263 + 8643143 = 8643406
269 + 8643137 = 8643406
347 + 8643059 = 8643406
353 + 8643053 = 8643406

Showing the first eight; more decompositions exist.
