Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720232, here are decompositions:

5 + 8720227 = 8720232
41 + 8720191 = 8720232
43 + 8720189 = 8720232
61 + 8720171 = 8720232
71 + 8720161 = 8720232
113 + 8720119 = 8720232
151 + 8720081 = 8720232
233 + 8719999 = 8720232

Showing the first eight; more decompositions exist.
