Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6386, here are decompositions:

7 + 6379 = 6386
13 + 6373 = 6386
19 + 6367 = 6386
43 + 6343 = 6386
109 + 6277 = 6386
139 + 6247 = 6386
157 + 6229 = 6386
223 + 6163 = 6386

Showing the first eight; more decompositions exist.
