Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153998, here are decompositions:

7 + 153991 = 153998
109 + 153889 = 153998
127 + 153871 = 153998
157 + 153841 = 153998
181 + 153817 = 153998
241 + 153757 = 153998
349 + 153649 = 153998
409 + 153589 = 153998

Showing the first eight; more decompositions exist.
