Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42906, here are decompositions:

5 + 42901 = 42906
7 + 42899 = 42906
43 + 42863 = 42906
47 + 42859 = 42906
53 + 42853 = 42906
67 + 42839 = 42906
109 + 42797 = 42906
113 + 42793 = 42906

Showing the first eight; more decompositions exist.
