Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139848, here are decompositions:

11 + 139837 = 139848
17 + 139831 = 139848
47 + 139801 = 139848
61 + 139787 = 139848
89 + 139759 = 139848
101 + 139747 = 139848
109 + 139739 = 139848
127 + 139721 = 139848

Showing the first eight; more decompositions exist.
