Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188198, here are decompositions:

19 + 188179 = 188198
61 + 188137 = 188198
181 + 188017 = 188198
211 + 187987 = 188198
271 + 187927 = 188198
277 + 187921 = 188198
337 + 187861 = 188198
487 + 187711 = 188198

Showing the first eight; more decompositions exist.
