Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137526, here are decompositions:

7 + 137519 = 137526
19 + 137507 = 137526
43 + 137483 = 137526
73 + 137453 = 137526
79 + 137447 = 137526
83 + 137443 = 137526
89 + 137437 = 137526
113 + 137413 = 137526

Showing the first eight; more decompositions exist.
