Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16100, here are decompositions:

3 + 16097 = 16100
13 + 16087 = 16100
31 + 16069 = 16100
37 + 16063 = 16100
43 + 16057 = 16100
67 + 16033 = 16100
109 + 15991 = 16100
127 + 15973 = 16100

Showing the first eight; more decompositions exist.
