Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72248, here are decompositions:

19 + 72229 = 72248
37 + 72211 = 72248
79 + 72169 = 72248
109 + 72139 = 72248
139 + 72109 = 72248
157 + 72091 = 72248
229 + 72019 = 72248
277 + 71971 = 72248

Showing the first eight; more decompositions exist.
