Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137502, here are decompositions:

11 + 137491 = 137502
19 + 137483 = 137502
59 + 137443 = 137502
89 + 137413 = 137502
103 + 137399 = 137502
109 + 137393 = 137502
139 + 137363 = 137502
149 + 137353 = 137502

Showing the first eight; more decompositions exist.
