Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15946, here are decompositions:

23 + 15923 = 15946
59 + 15887 = 15946
137 + 15809 = 15946
149 + 15797 = 15946
173 + 15773 = 15946
179 + 15767 = 15946
197 + 15749 = 15946
263 + 15683 = 15946

Showing the first eight; more decompositions exist.
