Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172998, here are decompositions:

5 + 172993 = 172998
11 + 172987 = 172998
17 + 172981 = 172998
29 + 172969 = 172998
127 + 172871 = 172998
131 + 172867 = 172998
139 + 172859 = 172998
149 + 172849 = 172998

Showing the first eight; more decompositions exist.
