Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42186, here are decompositions:

5 + 42181 = 42186
7 + 42179 = 42186
17 + 42169 = 42186
29 + 42157 = 42186
47 + 42139 = 42186
97 + 42089 = 42186
103 + 42083 = 42186
113 + 42073 = 42186

Showing the first eight; more decompositions exist.
