Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72132, here are decompositions:

23 + 72109 = 72132
29 + 72103 = 72132
31 + 72101 = 72132
41 + 72091 = 72132
43 + 72089 = 72132
59 + 72073 = 72132
79 + 72053 = 72132
89 + 72043 = 72132

Showing the first eight; more decompositions exist.
