Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189668, here are decompositions:

7 + 189661 = 189668
109 + 189559 = 189668
139 + 189529 = 189668
151 + 189517 = 189668
229 + 189439 = 189668
277 + 189391 = 189668
307 + 189361 = 189668
331 + 189337 = 189668

Showing the first eight; more decompositions exist.
