Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172226, here are decompositions:

3 + 172223 = 172226
7 + 172219 = 172226
13 + 172213 = 172226
73 + 172153 = 172226
79 + 172147 = 172226
157 + 172069 = 172226
199 + 172027 = 172226
337 + 171889 = 172226

Showing the first eight; more decompositions exist.
