Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649626, here are decompositions:

3 + 8649623 = 8649626
109 + 8649517 = 8649626
157 + 8649469 = 8649626
163 + 8649463 = 8649626
277 + 8649349 = 8649626
283 + 8649343 = 8649626
373 + 8649253 = 8649626
439 + 8649187 = 8649626

Showing the first eight; more decompositions exist.
