Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111524, here are decompositions:

3 + 111521 = 111524
31 + 111493 = 111524
37 + 111487 = 111524
97 + 111427 = 111524
151 + 111373 = 111524
223 + 111301 = 111524
271 + 111253 = 111524
307 + 111217 = 111524

Showing the first eight; more decompositions exist.
