Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72628, here are decompositions:

5 + 72623 = 72628
11 + 72617 = 72628
131 + 72497 = 72628
167 + 72461 = 72628
197 + 72431 = 72628
359 + 72269 = 72628
401 + 72227 = 72628
461 + 72167 = 72628

Showing the first eight; more decompositions exist.
