Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148986, here are decompositions:

29 + 148957 = 148986
37 + 148949 = 148986
53 + 148933 = 148986
59 + 148927 = 148986
73 + 148913 = 148986
113 + 148873 = 148986
127 + 148859 = 148986
157 + 148829 = 148986

Showing the first eight; more decompositions exist.
