Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647432, here are decompositions:

23 + 8647409 = 8647432
41 + 8647391 = 8647432
83 + 8647349 = 8647432
179 + 8647253 = 8647432
239 + 8647193 = 8647432
251 + 8647181 = 8647432
293 + 8647139 = 8647432
389 + 8647043 = 8647432

Showing the first eight; more decompositions exist.
