Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189732, here are decompositions:

19 + 189713 = 189732
31 + 189701 = 189732
41 + 189691 = 189732
61 + 189671 = 189732
71 + 189661 = 189732
79 + 189653 = 189732
89 + 189643 = 189732
113 + 189619 = 189732

Showing the first eight; more decompositions exist.
