Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647292, here are decompositions:

19 + 8647273 = 8647292
61 + 8647231 = 8647292
109 + 8647183 = 8647292
163 + 8647129 = 8647292
229 + 8647063 = 8647292
271 + 8647021 = 8647292
331 + 8646961 = 8647292
349 + 8646943 = 8647292

Showing the first eight; more decompositions exist.
