Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172992, here are decompositions:

5 + 172987 = 172992
11 + 172981 = 172992
19 + 172973 = 172992
23 + 172969 = 172992
59 + 172933 = 172992
109 + 172883 = 172992
139 + 172853 = 172992
163 + 172829 = 172992

Showing the first eight; more decompositions exist.
