Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172986, here are decompositions:

5 + 172981 = 172986
13 + 172973 = 172986
17 + 172969 = 172986
53 + 172933 = 172986
103 + 172883 = 172986
109 + 172877 = 172986
127 + 172859 = 172986
137 + 172849 = 172986

Showing the first eight; more decompositions exist.
