Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10388, here are decompositions:

19 + 10369 = 10388
31 + 10357 = 10388
67 + 10321 = 10388
211 + 10177 = 10388
229 + 10159 = 10388
277 + 10111 = 10388
349 + 10039 = 10388
379 + 10009 = 10388

Showing the first eight; more decompositions exist.
