Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16972, here are decompositions:

29 + 16943 = 16972
41 + 16931 = 16972
71 + 16901 = 16972
83 + 16889 = 16972
89 + 16883 = 16972
101 + 16871 = 16972
149 + 16823 = 16972
269 + 16703 = 16972

Showing the first eight; more decompositions exist.
