Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148998, here are decompositions:

7 + 148991 = 148998
37 + 148961 = 148998
41 + 148957 = 148998
67 + 148931 = 148998
71 + 148927 = 148998
107 + 148891 = 148998
131 + 148867 = 148998
137 + 148861 = 148998

Showing the first eight; more decompositions exist.
