Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728338, here are decompositions:

7 + 8728331 = 8728338
29 + 8728309 = 8728338
97 + 8728241 = 8728338
127 + 8728211 = 8728338
131 + 8728207 = 8728338
191 + 8728147 = 8728338
349 + 8727989 = 8728338
401 + 8727937 = 8728338

Showing the first eight; more decompositions exist.
