Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137208, here are decompositions:

7 + 137201 = 137208
11 + 137197 = 137208
17 + 137191 = 137208
31 + 137177 = 137208
61 + 137147 = 137208
89 + 137119 = 137208
131 + 137077 = 137208
179 + 137029 = 137208

Showing the first eight; more decompositions exist.
