Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149268, here are decompositions:

11 + 149257 = 149268
17 + 149251 = 149268
19 + 149249 = 149268
29 + 149239 = 149268
71 + 149197 = 149268
107 + 149161 = 149268
109 + 149159 = 149268
149 + 149119 = 149268

Showing the first eight; more decompositions exist.
