Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111582, here are decompositions:

5 + 111577 = 111582
43 + 111539 = 111582
61 + 111521 = 111582
73 + 111509 = 111582
89 + 111493 = 111582
139 + 111443 = 111582
151 + 111431 = 111582
173 + 111409 = 111582

Showing the first eight; more decompositions exist.
