Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189774, here are decompositions:

7 + 189767 = 189774
17 + 189757 = 189774
31 + 189743 = 189774
41 + 189733 = 189774
61 + 189713 = 189774
73 + 189701 = 189774
83 + 189691 = 189774
103 + 189671 = 189774

Showing the first eight; more decompositions exist.
