Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72028, here are decompositions:

29 + 71999 = 72028
41 + 71987 = 72028
149 + 71879 = 72028
167 + 71861 = 72028
179 + 71849 = 72028
191 + 71837 = 72028
239 + 71789 = 72028
251 + 71777 = 72028

Showing the first eight; more decompositions exist.
