Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639346, here are decompositions:

47 + 8639299 = 8639346
73 + 8639273 = 8639346
83 + 8639263 = 8639346
97 + 8639249 = 8639346
127 + 8639219 = 8639346
139 + 8639207 = 8639346
193 + 8639153 = 8639346
197 + 8639149 = 8639346

Showing the first eight; more decompositions exist.
