Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647246, here are decompositions:

17 + 8647229 = 8647246
53 + 8647193 = 8647246
89 + 8647157 = 8647246
107 + 8647139 = 8647246
239 + 8647007 = 8647246
317 + 8646929 = 8647246
347 + 8646899 = 8647246
467 + 8646779 = 8647246

Showing the first eight; more decompositions exist.
