Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139782, here are decompositions:

23 + 139759 = 139782
29 + 139753 = 139782
43 + 139739 = 139782
53 + 139729 = 139782
61 + 139721 = 139782
73 + 139709 = 139782
79 + 139703 = 139782
101 + 139681 = 139782

Showing the first eight; more decompositions exist.
