Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6530, here are decompositions:

61 + 6469 = 6530
79 + 6451 = 6530
103 + 6427 = 6530
109 + 6421 = 6530
151 + 6379 = 6530
157 + 6373 = 6530
163 + 6367 = 6530
193 + 6337 = 6530

Showing the first eight; more decompositions exist.
