Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156858, here are decompositions:

17 + 156841 = 156858
41 + 156817 = 156858
59 + 156799 = 156858
61 + 156797 = 156858
109 + 156749 = 156858
131 + 156727 = 156858
139 + 156719 = 156858
151 + 156707 = 156858

Showing the first eight; more decompositions exist.
