Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172406, here are decompositions:

7 + 172399 = 172406
109 + 172297 = 172406
127 + 172279 = 172406
163 + 172243 = 172406
193 + 172213 = 172406
313 + 172093 = 172406
337 + 172069 = 172406
379 + 172027 = 172406

Showing the first eight; more decompositions exist.
