Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642356, here are decompositions:

53 + 8642303 = 8642356
167 + 8642189 = 8642356
197 + 8642159 = 8642356
257 + 8642099 = 8642356
293 + 8642063 = 8642356
353 + 8642003 = 8642356
647 + 8641709 = 8642356
659 + 8641697 = 8642356

Showing the first eight; more decompositions exist.
