Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189804, here are decompositions:

5 + 189799 = 189804
7 + 189797 = 189804
37 + 189767 = 189804
47 + 189757 = 189804
61 + 189743 = 189804
71 + 189733 = 189804
103 + 189701 = 189804
107 + 189697 = 189804

Showing the first eight; more decompositions exist.
