Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113280, here are decompositions:

47 + 113233 = 113280
53 + 113227 = 113280
67 + 113213 = 113280
71 + 113209 = 113280
103 + 113177 = 113280
107 + 113173 = 113280
109 + 113171 = 113280
113 + 113167 = 113280

Showing the first eight; more decompositions exist.
