Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6418, here are decompositions:

29 + 6389 = 6418
59 + 6359 = 6418
89 + 6329 = 6418
101 + 6317 = 6418
107 + 6311 = 6418
131 + 6287 = 6418
149 + 6269 = 6418
197 + 6221 = 6418

Showing the first eight; more decompositions exist.
