Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189998, here are decompositions:

31 + 189967 = 189998
37 + 189961 = 189998
97 + 189901 = 189998
139 + 189859 = 189998
181 + 189817 = 189998
199 + 189799 = 189998
241 + 189757 = 189998
307 + 189691 = 189998

Showing the first eight; more decompositions exist.
