Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42028, here are decompositions:

5 + 42023 = 42028
11 + 42017 = 42028
29 + 41999 = 42028
47 + 41981 = 42028
59 + 41969 = 42028
71 + 41957 = 42028
101 + 41927 = 42028
131 + 41897 = 42028

Showing the first eight; more decompositions exist.
