Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189130, here are decompositions:

3 + 189127 = 189130
89 + 189041 = 189130
113 + 189017 = 189130
131 + 188999 = 189130
173 + 188957 = 189130
191 + 188939 = 189130
197 + 188933 = 189130
239 + 188891 = 189130

Showing the first eight; more decompositions exist.
