Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40284, here are decompositions:

7 + 40277 = 40284
31 + 40253 = 40284
43 + 40241 = 40284
47 + 40237 = 40284
53 + 40231 = 40284
71 + 40213 = 40284
107 + 40177 = 40284
131 + 40153 = 40284

Showing the first eight; more decompositions exist.
