Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639482, here are decompositions:

23 + 8639459 = 8639482
29 + 8639453 = 8639482
41 + 8639441 = 8639482
101 + 8639381 = 8639482
191 + 8639291 = 8639482
233 + 8639249 = 8639482
263 + 8639219 = 8639482
311 + 8639171 = 8639482

Showing the first eight; more decompositions exist.
