Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646342, here are decompositions:

13 + 8646329 = 8646342
43 + 8646299 = 8646342
73 + 8646269 = 8646342
83 + 8646259 = 8646342
109 + 8646233 = 8646342
179 + 8646163 = 8646342
223 + 8646119 = 8646342
239 + 8646103 = 8646342

Showing the first eight; more decompositions exist.
