Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72162, here are decompositions:

23 + 72139 = 72162
53 + 72109 = 72162
59 + 72103 = 72162
61 + 72101 = 72162
71 + 72091 = 72162
73 + 72089 = 72162
89 + 72073 = 72162
109 + 72053 = 72162

Showing the first eight; more decompositions exist.
