Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156906, here are decompositions:

5 + 156901 = 156906
7 + 156899 = 156906
19 + 156887 = 156906
73 + 156833 = 156906
83 + 156823 = 156906
89 + 156817 = 156906
107 + 156799 = 156906
109 + 156797 = 156906

Showing the first eight; more decompositions exist.
