Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633840, here are decompositions:

13 + 8633827 = 8633840
73 + 8633767 = 8633840
109 + 8633731 = 8633840
139 + 8633701 = 8633840
157 + 8633683 = 8633840
181 + 8633659 = 8633840
199 + 8633641 = 8633840
379 + 8633461 = 8633840

Showing the first eight; more decompositions exist.
