Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123732, here are decompositions:

5 + 123727 = 123732
13 + 123719 = 123732
31 + 123701 = 123732
71 + 123661 = 123732
79 + 123653 = 123732
101 + 123631 = 123732
113 + 123619 = 123732
131 + 123601 = 123732

Showing the first eight; more decompositions exist.
