Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2570, here are decompositions:

13 + 2557 = 2570
19 + 2551 = 2570
31 + 2539 = 2570
67 + 2503 = 2570
97 + 2473 = 2570
103 + 2467 = 2570
181 + 2389 = 2570
193 + 2377 = 2570

Showing the first eight; more decompositions exist.
