Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740128, here are decompositions:

11 + 8740117 = 8740128
17 + 8740111 = 8740128
31 + 8740097 = 8740128
41 + 8740087 = 8740128
167 + 8739961 = 8740128
191 + 8739937 = 8740128
211 + 8739917 = 8740128
227 + 8739901 = 8740128

Showing the first eight; more decompositions exist.
