Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137490, here are decompositions:

7 + 137483 = 137490
13 + 137477 = 137490
37 + 137453 = 137490
43 + 137447 = 137490
47 + 137443 = 137490
53 + 137437 = 137490
97 + 137393 = 137490
103 + 137387 = 137490

Showing the first eight; more decompositions exist.
