Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639452, here are decompositions:

11 + 8639441 = 8639452
71 + 8639381 = 8639452
89 + 8639363 = 8639452
179 + 8639273 = 8639452
191 + 8639261 = 8639452
233 + 8639219 = 8639452
281 + 8639171 = 8639452
389 + 8639063 = 8639452

Showing the first eight; more decompositions exist.
