Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173966, here are decompositions:

43 + 173923 = 173966
127 + 173839 = 173966
139 + 173827 = 173966
193 + 173773 = 173966
223 + 173743 = 173966
283 + 173683 = 173966
307 + 173659 = 173966
337 + 173629 = 173966

Showing the first eight; more decompositions exist.
