Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172122, here are decompositions:

29 + 172093 = 172122
43 + 172079 = 172122
53 + 172069 = 172122
73 + 172049 = 172122
101 + 172021 = 172122
113 + 172009 = 172122
193 + 171929 = 172122
199 + 171923 = 172122

Showing the first eight; more decompositions exist.
