Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72182, here are decompositions:

13 + 72169 = 72182
43 + 72139 = 72182
73 + 72109 = 72182
79 + 72103 = 72182
109 + 72073 = 72182
139 + 72043 = 72182
151 + 72031 = 72182
163 + 72019 = 72182

Showing the first eight; more decompositions exist.
