Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137406, here are decompositions:

7 + 137399 = 137406
13 + 137393 = 137406
19 + 137387 = 137406
23 + 137383 = 137406
37 + 137369 = 137406
43 + 137363 = 137406
47 + 137359 = 137406
53 + 137353 = 137406

Showing the first eight; more decompositions exist.
