Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732128, here are decompositions:

5 + 8732123 = 8732128
11 + 8732117 = 8732128
47 + 8732081 = 8732128
101 + 8732027 = 8732128
137 + 8731991 = 8732128
149 + 8731979 = 8732128
191 + 8731937 = 8732128
227 + 8731901 = 8732128

Showing the first eight; more decompositions exist.
