Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728038, here are decompositions:

101 + 8727937 = 8728038
107 + 8727931 = 8728038
131 + 8727907 = 8728038
139 + 8727899 = 8728038
167 + 8727871 = 8728038
181 + 8727857 = 8728038
229 + 8727809 = 8728038
271 + 8727767 = 8728038

Showing the first eight; more decompositions exist.
