Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172950, here are decompositions:

17 + 172933 = 172950
67 + 172883 = 172950
73 + 172877 = 172950
79 + 172871 = 172950
83 + 172867 = 172950
97 + 172853 = 172950
101 + 172849 = 172950
149 + 172801 = 172950

Showing the first eight; more decompositions exist.
