Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111668, here are decompositions:

31 + 111637 = 111668
181 + 111487 = 111668
229 + 111439 = 111668
241 + 111427 = 111668
331 + 111337 = 111668
367 + 111301 = 111668
397 + 111271 = 111668
439 + 111229 = 111668

Showing the first eight; more decompositions exist.
