Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111608, here are decompositions:

31 + 111577 = 111608
181 + 111427 = 111608
199 + 111409 = 111608
271 + 111337 = 111608
307 + 111301 = 111608
337 + 111271 = 111608
379 + 111229 = 111608
397 + 111211 = 111608

Showing the first eight; more decompositions exist.
