Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647202, here are decompositions:

19 + 8647183 = 8647202
73 + 8647129 = 8647202
79 + 8647123 = 8647202
139 + 8647063 = 8647202
181 + 8647021 = 8647202
241 + 8646961 = 8647202
313 + 8646889 = 8647202
349 + 8646853 = 8647202

Showing the first eight; more decompositions exist.
