Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137556, here are decompositions:

19 + 137537 = 137556
37 + 137519 = 137556
73 + 137483 = 137556
79 + 137477 = 137556
103 + 137453 = 137556
109 + 137447 = 137556
113 + 137443 = 137556
157 + 137399 = 137556

Showing the first eight; more decompositions exist.
