Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6448, here are decompositions:

59 + 6389 = 6448
89 + 6359 = 6448
131 + 6317 = 6448
137 + 6311 = 6448
149 + 6299 = 6448
179 + 6269 = 6448
191 + 6257 = 6448
227 + 6221 = 6448

Showing the first eight; more decompositions exist.
