Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42056, here are decompositions:

13 + 42043 = 42056
37 + 42019 = 42056
43 + 42013 = 42056
73 + 41983 = 42056
97 + 41959 = 42056
103 + 41953 = 42056
109 + 41947 = 42056
163 + 41893 = 42056

Showing the first eight; more decompositions exist.
