Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72280, here are decompositions:

3 + 72277 = 72280
11 + 72269 = 72280
29 + 72251 = 72280
53 + 72227 = 72280
59 + 72221 = 72280
107 + 72173 = 72280
113 + 72167 = 72280
179 + 72101 = 72280

Showing the first eight; more decompositions exist.
