Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154998, here are decompositions:

7 + 154991 = 154998
17 + 154981 = 154998
61 + 154937 = 154998
71 + 154927 = 154998
101 + 154897 = 154998
127 + 154871 = 154998
149 + 154849 = 154998
157 + 154841 = 154998

Showing the first eight; more decompositions exist.
