Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6488, here are decompositions:

7 + 6481 = 6488
19 + 6469 = 6488
37 + 6451 = 6488
61 + 6427 = 6488
67 + 6421 = 6488
109 + 6379 = 6488
127 + 6361 = 6488
151 + 6337 = 6488

Showing the first eight; more decompositions exist.
