Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6550, here are decompositions:

3 + 6547 = 6550
29 + 6521 = 6550
59 + 6491 = 6550
101 + 6449 = 6550
191 + 6359 = 6550
197 + 6353 = 6550
227 + 6323 = 6550
233 + 6317 = 6550

Showing the first eight; more decompositions exist.
