Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148970, here are decompositions:

13 + 148957 = 148970
37 + 148933 = 148970
43 + 148927 = 148970
79 + 148891 = 148970
97 + 148873 = 148970
103 + 148867 = 148970
109 + 148861 = 148970
223 + 148747 = 148970

Showing the first eight; more decompositions exist.
