Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139884, here are decompositions:

13 + 139871 = 139884
23 + 139861 = 139884
47 + 139837 = 139884
53 + 139831 = 139884
71 + 139813 = 139884
83 + 139801 = 139884
97 + 139787 = 139884
131 + 139753 = 139884

Showing the first eight; more decompositions exist.
