Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172098, here are decompositions:

5 + 172093 = 172098
19 + 172079 = 172098
29 + 172069 = 172098
67 + 172031 = 172098
71 + 172027 = 172098
89 + 172009 = 172098
97 + 172001 = 172098
151 + 171947 = 172098

Showing the first eight; more decompositions exist.
