Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627444, here are decompositions:

3 + 8627441 = 8627444
13 + 8627431 = 8627444
73 + 8627371 = 8627444
103 + 8627341 = 8627444
193 + 8627251 = 8627444
271 + 8627173 = 8627444
277 + 8627167 = 8627444
283 + 8627161 = 8627444

Showing the first eight; more decompositions exist.
