Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158020, here are decompositions:

3 + 158017 = 158020
11 + 158009 = 158020
17 + 158003 = 158020
29 + 157991 = 158020
89 + 157931 = 158020
113 + 157907 = 158020
131 + 157889 = 158020
179 + 157841 = 158020

Showing the first eight; more decompositions exist.
