Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639320, here are decompositions:

29 + 8639291 = 8639320
47 + 8639273 = 8639320
59 + 8639261 = 8639320
71 + 8639249 = 8639320
101 + 8639219 = 8639320
113 + 8639207 = 8639320
149 + 8639171 = 8639320
167 + 8639153 = 8639320

Showing the first eight; more decompositions exist.
