Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188998, here are decompositions:

41 + 188957 = 188998
59 + 188939 = 188998
71 + 188927 = 188998
107 + 188891 = 188998
137 + 188861 = 188998
167 + 188831 = 188998
197 + 188801 = 188998
269 + 188729 = 188998

Showing the first eight; more decompositions exist.
