Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139752, here are decompositions:

5 + 139747 = 139752
13 + 139739 = 139752
23 + 139729 = 139752
31 + 139721 = 139752
43 + 139709 = 139752
71 + 139681 = 139752
89 + 139663 = 139752
163 + 139589 = 139752

Showing the first eight; more decompositions exist.
