Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137568, here are decompositions:

31 + 137537 = 137568
61 + 137507 = 137568
131 + 137437 = 137568
181 + 137387 = 137568
199 + 137369 = 137568
227 + 137341 = 137568
229 + 137339 = 137568
317 + 137251 = 137568

Showing the first eight; more decompositions exist.
