Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111998, here are decompositions:

79 + 111919 = 111998
127 + 111871 = 111998
151 + 111847 = 111998
199 + 111799 = 111998
277 + 111721 = 111998
331 + 111667 = 111998
421 + 111577 = 111998
571 + 111427 = 111998

Showing the first eight; more decompositions exist.
