Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6470, here are decompositions:

19 + 6451 = 6470
43 + 6427 = 6470
73 + 6397 = 6470
97 + 6373 = 6470
103 + 6367 = 6470
109 + 6361 = 6470
127 + 6343 = 6470
193 + 6277 = 6470

Showing the first eight; more decompositions exist.
