Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148950, here are decompositions:

17 + 148933 = 148950
19 + 148931 = 148950
23 + 148927 = 148950
29 + 148921 = 148950
37 + 148913 = 148950
59 + 148891 = 148950
83 + 148867 = 148950
89 + 148861 = 148950

Showing the first eight; more decompositions exist.
