Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72112, here are decompositions:

3 + 72109 = 72112
11 + 72101 = 72112
23 + 72089 = 72112
59 + 72053 = 72112
113 + 71999 = 72112
149 + 71963 = 72112
179 + 71933 = 72112
233 + 71879 = 72112

Showing the first eight; more decompositions exist.
