Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642794, here are decompositions:

47 + 8642747 = 8642794
71 + 8642723 = 8642794
227 + 8642567 = 8642794
491 + 8642303 = 8642794
557 + 8642237 = 8642794
647 + 8642147 = 8642794
653 + 8642141 = 8642794
683 + 8642111 = 8642794

Showing the first eight; more decompositions exist.
