Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16090, here are decompositions:

3 + 16087 = 16090
17 + 16073 = 16090
23 + 16067 = 16090
29 + 16061 = 16090
83 + 16007 = 16090
89 + 16001 = 16090
131 + 15959 = 16090
167 + 15923 = 16090

Showing the first eight; more decompositions exist.
