Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189700, here are decompositions:

3 + 189697 = 189700
29 + 189671 = 189700
47 + 189653 = 189700
83 + 189617 = 189700
101 + 189599 = 189700
107 + 189593 = 189700
191 + 189509 = 189700
227 + 189473 = 189700

Showing the first eight; more decompositions exist.
