Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137544, here are decompositions:

7 + 137537 = 137544
37 + 137507 = 137544
53 + 137491 = 137544
61 + 137483 = 137544
67 + 137477 = 137544
97 + 137447 = 137544
101 + 137443 = 137544
107 + 137437 = 137544

Showing the first eight; more decompositions exist.
