Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158880, here are decompositions:

13 + 158867 = 158880
17 + 158863 = 158880
31 + 158849 = 158880
37 + 158843 = 158880
89 + 158791 = 158880
103 + 158777 = 158880
109 + 158771 = 158880
131 + 158749 = 158880

Showing the first eight; more decompositions exist.
