Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40264, here are decompositions:

11 + 40253 = 40264
23 + 40241 = 40264
71 + 40193 = 40264
101 + 40163 = 40264
113 + 40151 = 40264
137 + 40127 = 40264
227 + 40037 = 40264
233 + 40031 = 40264

Showing the first eight; more decompositions exist.
