Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42112, here are decompositions:

11 + 42101 = 42112
23 + 42089 = 42112
29 + 42083 = 42112
41 + 42071 = 42112
89 + 42023 = 42112
113 + 41999 = 42112
131 + 41981 = 42112
233 + 41879 = 42112

Showing the first eight; more decompositions exist.
