Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647546, here are decompositions:

137 + 8647409 = 8647546
179 + 8647367 = 8647546
197 + 8647349 = 8647546
269 + 8647277 = 8647546
293 + 8647253 = 8647546
317 + 8647229 = 8647546
353 + 8647193 = 8647546
389 + 8647157 = 8647546

Showing the first eight; more decompositions exist.
