Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137250, here are decompositions:

11 + 137239 = 137250
31 + 137219 = 137250
41 + 137209 = 137250
53 + 137197 = 137250
59 + 137191 = 137250
67 + 137183 = 137250
73 + 137177 = 137250
97 + 137153 = 137250

Showing the first eight; more decompositions exist.
