Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173990, here are decompositions:

13 + 173977 = 173990
67 + 173923 = 173990
73 + 173917 = 173990
139 + 173851 = 173990
151 + 173839 = 173990
163 + 173827 = 173990
211 + 173779 = 173990
277 + 173713 = 173990

Showing the first eight; more decompositions exist.
