Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639370, here are decompositions:

7 + 8639363 = 8639370
23 + 8639347 = 8639370
71 + 8639299 = 8639370
79 + 8639291 = 8639370
97 + 8639273 = 8639370
107 + 8639263 = 8639370
109 + 8639261 = 8639370
151 + 8639219 = 8639370

Showing the first eight; more decompositions exist.
