Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647486, here are decompositions:

17 + 8647469 = 8647486
137 + 8647349 = 8647486
233 + 8647253 = 8647486
257 + 8647229 = 8647486
293 + 8647193 = 8647486
347 + 8647139 = 8647486
359 + 8647127 = 8647486
443 + 8647043 = 8647486

Showing the first eight; more decompositions exist.
