Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639462, here are decompositions:

3 + 8639459 = 8639462
19 + 8639443 = 8639462
61 + 8639401 = 8639462
163 + 8639299 = 8639462
199 + 8639263 = 8639462
211 + 8639251 = 8639462
313 + 8639149 = 8639462
331 + 8639131 = 8639462

Showing the first eight; more decompositions exist.
