Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156828, here are decompositions:

5 + 156823 = 156828
11 + 156817 = 156828
29 + 156799 = 156828
31 + 156797 = 156828
47 + 156781 = 156828
79 + 156749 = 156828
101 + 156727 = 156828
109 + 156719 = 156828

Showing the first eight; more decompositions exist.
