Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173984, here are decompositions:

3 + 173981 = 173984
7 + 173977 = 173984
61 + 173923 = 173984
67 + 173917 = 173984
157 + 173827 = 173984
211 + 173773 = 173984
241 + 173743 = 173984
271 + 173713 = 173984

Showing the first eight; more decompositions exist.
