Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16990, here are decompositions:

3 + 16987 = 16990
11 + 16979 = 16990
47 + 16943 = 16990
53 + 16937 = 16990
59 + 16931 = 16990
89 + 16901 = 16990
101 + 16889 = 16990
107 + 16883 = 16990

Showing the first eight; more decompositions exist.
