Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156900, here are decompositions:

13 + 156887 = 156900
59 + 156841 = 156900
67 + 156833 = 156900
83 + 156817 = 156900
101 + 156799 = 156900
103 + 156797 = 156900
151 + 156749 = 156900
167 + 156733 = 156900

Showing the first eight; more decompositions exist.
