Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639372, here are decompositions:

73 + 8639299 = 8639372
109 + 8639263 = 8639372
211 + 8639161 = 8639372
223 + 8639149 = 8639372
229 + 8639143 = 8639372
241 + 8639131 = 8639372
283 + 8639089 = 8639372
373 + 8638999 = 8639372

Showing the first eight; more decompositions exist.
