Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189756, here are decompositions:

13 + 189743 = 189756
23 + 189733 = 189756
43 + 189713 = 189756
59 + 189697 = 189756
103 + 189653 = 189756
113 + 189643 = 189756
137 + 189619 = 189756
139 + 189617 = 189756

Showing the first eight; more decompositions exist.
