Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42732, here are decompositions:

5 + 42727 = 42732
13 + 42719 = 42732
23 + 42709 = 42732
29 + 42703 = 42732
31 + 42701 = 42732
43 + 42689 = 42732
83 + 42649 = 42732
89 + 42643 = 42732

Showing the first eight; more decompositions exist.
