Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189972, here are decompositions:

5 + 189967 = 189972
11 + 189961 = 189972
23 + 189949 = 189972
43 + 189929 = 189972
59 + 189913 = 189972
71 + 189901 = 189972
113 + 189859 = 189972
149 + 189823 = 189972

Showing the first eight; more decompositions exist.
