Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189790, here are decompositions:

23 + 189767 = 189790
47 + 189743 = 189790
89 + 189701 = 189790
137 + 189653 = 189790
173 + 189617 = 189790
191 + 189599 = 189790
197 + 189593 = 189790
281 + 189509 = 189790

Showing the first eight; more decompositions exist.
