Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111560, here are decompositions:

67 + 111493 = 111560
73 + 111487 = 111560
151 + 111409 = 111560
223 + 111337 = 111560
307 + 111253 = 111560
331 + 111229 = 111560
349 + 111211 = 111560
373 + 111187 = 111560

Showing the first eight; more decompositions exist.
