Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137396, here are decompositions:

3 + 137393 = 137396
13 + 137383 = 137396
37 + 137359 = 137396
43 + 137353 = 137396
157 + 137239 = 137396
199 + 137197 = 137396
277 + 137119 = 137396
307 + 137089 = 137396

Showing the first eight; more decompositions exist.
