Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140028, here are decompositions:

19 + 140009 = 140028
29 + 139999 = 140028
37 + 139991 = 140028
41 + 139987 = 140028
47 + 139981 = 140028
59 + 139969 = 140028
61 + 139967 = 140028
89 + 139939 = 140028

Showing the first eight; more decompositions exist.
