Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166974, here are decompositions:

7 + 166967 = 166974
43 + 166931 = 166974
103 + 166871 = 166974
107 + 166867 = 166974
113 + 166861 = 166974
127 + 166847 = 166974
131 + 166843 = 166974
151 + 166823 = 166974

Showing the first eight; more decompositions exist.
