Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120828, here are decompositions:

5 + 120823 = 120828
11 + 120817 = 120828
17 + 120811 = 120828
61 + 120767 = 120828
79 + 120749 = 120828
89 + 120739 = 120828
107 + 120721 = 120828
137 + 120691 = 120828

Showing the first eight; more decompositions exist.
