Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189954, here are decompositions:

5 + 189949 = 189954
7 + 189947 = 189954
41 + 189913 = 189954
53 + 189901 = 189954
67 + 189887 = 189954
73 + 189881 = 189954
101 + 189853 = 189954
103 + 189851 = 189954

Showing the first eight; more decompositions exist.
