Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158970, here are decompositions:

11 + 158959 = 158970
29 + 158941 = 158970
43 + 158927 = 158970
47 + 158923 = 158970
61 + 158909 = 158970
89 + 158881 = 158970
103 + 158867 = 158970
107 + 158863 = 158970

Showing the first eight; more decompositions exist.
