Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111558, here are decompositions:

19 + 111539 = 111558
37 + 111521 = 111558
61 + 111497 = 111558
67 + 111491 = 111558
71 + 111487 = 111558
127 + 111431 = 111558
131 + 111427 = 111558
149 + 111409 = 111558

Showing the first eight; more decompositions exist.
