Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6750, here are decompositions:

13 + 6737 = 6750
17 + 6733 = 6750
31 + 6719 = 6750
41 + 6709 = 6750
47 + 6703 = 6750
59 + 6691 = 6750
61 + 6689 = 6750
71 + 6679 = 6750

Showing the first eight; more decompositions exist.
