Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643794, here are decompositions:

7 + 8643787 = 8643794
37 + 8643757 = 8643794
73 + 8643721 = 8643794
97 + 8643697 = 8643794
163 + 8643631 = 8643794
307 + 8643487 = 8643794
337 + 8643457 = 8643794
457 + 8643337 = 8643794

Showing the first eight; more decompositions exist.
