Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172136, here are decompositions:

43 + 172093 = 172136
67 + 172069 = 172136
109 + 172027 = 172136
127 + 172009 = 172136
199 + 171937 = 172136
313 + 171823 = 172136
337 + 171799 = 172136
373 + 171763 = 172136

Showing the first eight; more decompositions exist.
