Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32100, here are decompositions:

11 + 32089 = 32100
17 + 32083 = 32100
23 + 32077 = 32100
31 + 32069 = 32100
37 + 32063 = 32100
41 + 32059 = 32100
43 + 32057 = 32100
71 + 32029 = 32100

Showing the first eight; more decompositions exist.
