Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173998, here are decompositions:

5 + 173993 = 173998
17 + 173981 = 173998
29 + 173969 = 173998
89 + 173909 = 173998
101 + 173897 = 173998
107 + 173891 = 173998
131 + 173867 = 173998
137 + 173861 = 173998

Showing the first eight; more decompositions exist.
