Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 570, here are decompositions:

7 + 563 = 570
13 + 557 = 570
23 + 547 = 570
29 + 541 = 570
47 + 523 = 570
61 + 509 = 570
67 + 503 = 570
71 + 499 = 570

Showing the first eight; more decompositions exist.
