Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189956, here are decompositions:

7 + 189949 = 189956
43 + 189913 = 189956
79 + 189877 = 189956
97 + 189859 = 189956
103 + 189853 = 189956
139 + 189817 = 189956
157 + 189799 = 189956
199 + 189757 = 189956

Showing the first eight; more decompositions exist.
