Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158118, here are decompositions:

5 + 158113 = 158118
41 + 158077 = 158118
47 + 158071 = 158118
71 + 158047 = 158118
89 + 158029 = 158118
101 + 158017 = 158118
109 + 158009 = 158118
127 + 157991 = 158118

Showing the first eight; more decompositions exist.
