Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152820, here are decompositions:

11 + 152809 = 152820
29 + 152791 = 152820
37 + 152783 = 152820
43 + 152777 = 152820
53 + 152767 = 152820
67 + 152753 = 152820
97 + 152723 = 152820
103 + 152717 = 152820

Showing the first eight; more decompositions exist.
