Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172184, here are decompositions:

3 + 172181 = 172184
13 + 172171 = 172184
31 + 172153 = 172184
37 + 172147 = 172184
157 + 172027 = 172184
163 + 172021 = 172184
307 + 171877 = 172184
373 + 171811 = 172184

Showing the first eight; more decompositions exist.
