Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149208, here are decompositions:

11 + 149197 = 149208
47 + 149161 = 149208
89 + 149119 = 149208
97 + 149111 = 149208
107 + 149101 = 149208
109 + 149099 = 149208
131 + 149077 = 149208
139 + 149069 = 149208

Showing the first eight; more decompositions exist.
