Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639444, here are decompositions:

3 + 8639441 = 8639444
31 + 8639413 = 8639444
43 + 8639401 = 8639444
97 + 8639347 = 8639444
181 + 8639263 = 8639444
193 + 8639251 = 8639444
283 + 8639161 = 8639444
313 + 8639131 = 8639444

Showing the first eight; more decompositions exist.
