Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139824, here are decompositions:

11 + 139813 = 139824
23 + 139801 = 139824
37 + 139787 = 139824
71 + 139753 = 139824
103 + 139721 = 139824
127 + 139697 = 139824
163 + 139661 = 139824
197 + 139627 = 139824

Showing the first eight; more decompositions exist.
