Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149928, here are decompositions:

7 + 149921 = 149928
17 + 149911 = 149928
19 + 149909 = 149928
29 + 149899 = 149928
61 + 149867 = 149928
67 + 149861 = 149928
89 + 149839 = 149928
101 + 149827 = 149928

Showing the first eight; more decompositions exist.
