Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189056, here are decompositions:

13 + 189043 = 189056
37 + 189019 = 189056
73 + 188983 = 189056
103 + 188953 = 189056
193 + 188863 = 189056
199 + 188857 = 189056
223 + 188833 = 189056
229 + 188827 = 189056

Showing the first eight; more decompositions exist.
