Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72156, here are decompositions:

17 + 72139 = 72156
47 + 72109 = 72156
53 + 72103 = 72156
67 + 72089 = 72156
79 + 72077 = 72156
83 + 72073 = 72156
103 + 72053 = 72156
109 + 72047 = 72156

Showing the first eight; more decompositions exist.
