Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42876, here are decompositions:

13 + 42863 = 42876
17 + 42859 = 42876
23 + 42853 = 42876
37 + 42839 = 42876
47 + 42829 = 42876
79 + 42797 = 42876
83 + 42793 = 42876
89 + 42787 = 42876

Showing the first eight; more decompositions exist.
