Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734240, here are decompositions:

3 + 8734237 = 8734240
17 + 8734223 = 8734240
29 + 8734211 = 8734240
41 + 8734199 = 8734240
71 + 8734169 = 8734240
227 + 8734013 = 8734240
239 + 8734001 = 8734240
311 + 8733929 = 8734240

Showing the first eight; more decompositions exist.
