Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6610, here are decompositions:

3 + 6607 = 6610
11 + 6599 = 6610
29 + 6581 = 6610
41 + 6569 = 6610
47 + 6563 = 6610
59 + 6551 = 6610
89 + 6521 = 6610
137 + 6473 = 6610

Showing the first eight; more decompositions exist.
