Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148974, here are decompositions:

13 + 148961 = 148974
17 + 148957 = 148974
41 + 148933 = 148974
43 + 148931 = 148974
47 + 148927 = 148974
53 + 148921 = 148974
61 + 148913 = 148974
83 + 148891 = 148974

Showing the first eight; more decompositions exist.
