Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139812, here are decompositions:

11 + 139801 = 139812
53 + 139759 = 139812
59 + 139753 = 139812
73 + 139739 = 139812
83 + 139729 = 139812
103 + 139709 = 139812
109 + 139703 = 139812
131 + 139681 = 139812

Showing the first eight; more decompositions exist.
