Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159880, here are decompositions:

11 + 159869 = 159880
23 + 159857 = 159880
41 + 159839 = 159880
47 + 159833 = 159880
89 + 159791 = 159880
101 + 159779 = 159880
107 + 159773 = 159880
173 + 159707 = 159880

Showing the first eight; more decompositions exist.
