Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6570, here are decompositions:

7 + 6563 = 6570
17 + 6553 = 6570
19 + 6551 = 6570
23 + 6547 = 6570
41 + 6529 = 6570
79 + 6491 = 6570
89 + 6481 = 6570
97 + 6473 = 6570

Showing the first eight; more decompositions exist.
