Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137304, here are decompositions:

31 + 137273 = 137304
53 + 137251 = 137304
103 + 137201 = 137304
107 + 137197 = 137304
113 + 137191 = 137304
127 + 137177 = 137304
151 + 137153 = 137304
157 + 137147 = 137304

Showing the first eight; more decompositions exist.
