Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639404, here are decompositions:

3 + 8639401 = 8639404
23 + 8639381 = 8639404
41 + 8639363 = 8639404
113 + 8639291 = 8639404
131 + 8639273 = 8639404
197 + 8639207 = 8639404
227 + 8639177 = 8639404
233 + 8639171 = 8639404

Showing the first eight; more decompositions exist.
