Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111638, here are decompositions:

61 + 111577 = 111638
151 + 111487 = 111638
199 + 111439 = 111638
211 + 111427 = 111638
229 + 111409 = 111638
337 + 111301 = 111638
367 + 111271 = 111638
409 + 111229 = 111638

Showing the first eight; more decompositions exist.
