Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6402, here are decompositions:

5 + 6397 = 6402
13 + 6389 = 6402
23 + 6379 = 6402
29 + 6373 = 6402
41 + 6361 = 6402
43 + 6359 = 6402
59 + 6343 = 6402
73 + 6329 = 6402

Showing the first eight; more decompositions exist.
