Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189950, here are decompositions:

3 + 189947 = 189950
37 + 189913 = 189950
73 + 189877 = 189950
97 + 189853 = 189950
127 + 189823 = 189950
151 + 189799 = 189950
193 + 189757 = 189950
307 + 189643 = 189950

Showing the first eight; more decompositions exist.
