Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137508, here are decompositions:

17 + 137491 = 137508
31 + 137477 = 137508
61 + 137447 = 137508
71 + 137437 = 137508
109 + 137399 = 137508
139 + 137369 = 137508
149 + 137359 = 137508
167 + 137341 = 137508

Showing the first eight; more decompositions exist.
