Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42570, here are decompositions:

13 + 42557 = 42570
37 + 42533 = 42570
61 + 42509 = 42570
71 + 42499 = 42570
79 + 42491 = 42570
83 + 42487 = 42570
97 + 42473 = 42570
103 + 42467 = 42570

Showing the first eight; more decompositions exist.
