Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40388, here are decompositions:

31 + 40357 = 40388
37 + 40351 = 40388
151 + 40237 = 40388
157 + 40231 = 40388
199 + 40189 = 40388
211 + 40177 = 40388
277 + 40111 = 40388
349 + 40039 = 40388

Showing the first eight; more decompositions exist.
