Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6388, here are decompositions:

29 + 6359 = 6388
59 + 6329 = 6388
71 + 6317 = 6388
89 + 6299 = 6388
101 + 6287 = 6388
131 + 6257 = 6388
167 + 6221 = 6388
191 + 6197 = 6388

Showing the first eight; more decompositions exist.
