Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42810, here are decompositions:

13 + 42797 = 42810
17 + 42793 = 42810
23 + 42787 = 42810
37 + 42773 = 42810
43 + 42767 = 42810
59 + 42751 = 42810
67 + 42743 = 42810
73 + 42737 = 42810

Showing the first eight; more decompositions exist.
