Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189970, here are decompositions:

3 + 189967 = 189970
23 + 189947 = 189970
41 + 189929 = 189970
83 + 189887 = 189970
89 + 189881 = 189970
173 + 189797 = 189970
227 + 189743 = 189970
257 + 189713 = 189970

Showing the first eight; more decompositions exist.
