Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189188, here are decompositions:

19 + 189169 = 189188
37 + 189151 = 189188
61 + 189127 = 189188
127 + 189061 = 189188
277 + 188911 = 189188
331 + 188857 = 189188
397 + 188791 = 189188
409 + 188779 = 189188

Showing the first eight; more decompositions exist.
