Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111728, here are decompositions:

7 + 111721 = 111728
31 + 111697 = 111728
61 + 111667 = 111728
151 + 111577 = 111728
241 + 111487 = 111728
457 + 111271 = 111728
499 + 111229 = 111728
541 + 111187 = 111728

Showing the first eight; more decompositions exist.
