Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42866, here are decompositions:

3 + 42863 = 42866
7 + 42859 = 42866
13 + 42853 = 42866
37 + 42829 = 42866
73 + 42793 = 42866
79 + 42787 = 42866
139 + 42727 = 42866
157 + 42709 = 42866

Showing the first eight; more decompositions exist.
