Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189974, here are decompositions:

7 + 189967 = 189974
13 + 189961 = 189974
61 + 189913 = 189974
73 + 189901 = 189974
97 + 189877 = 189974
151 + 189823 = 189974
157 + 189817 = 189974
241 + 189733 = 189974

Showing the first eight; more decompositions exist.
