Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166998, here are decompositions:

11 + 166987 = 166998
19 + 166979 = 166998
31 + 166967 = 166998
67 + 166931 = 166998
79 + 166919 = 166998
89 + 166909 = 166998
127 + 166871 = 166998
131 + 166867 = 166998

Showing the first eight; more decompositions exist.
