Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149946, here are decompositions:

7 + 149939 = 149946
37 + 149909 = 149946
47 + 149899 = 149946
53 + 149893 = 149946
73 + 149873 = 149946
79 + 149867 = 149946
107 + 149839 = 149946
109 + 149837 = 149946

Showing the first eight; more decompositions exist.
