Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152838, here are decompositions:

5 + 152833 = 152838
17 + 152821 = 152838
19 + 152819 = 152838
29 + 152809 = 152838
47 + 152791 = 152838
61 + 152777 = 152838
71 + 152767 = 152838
109 + 152729 = 152838

Showing the first eight; more decompositions exist.
