Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6430, here are decompositions:

3 + 6427 = 6430
41 + 6389 = 6430
71 + 6359 = 6430
101 + 6329 = 6430
107 + 6323 = 6430
113 + 6317 = 6430
131 + 6299 = 6430
167 + 6263 = 6430

Showing the first eight; more decompositions exist.
