Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137558, here are decompositions:

67 + 137491 = 137558
199 + 137359 = 137558
307 + 137251 = 137558
349 + 137209 = 137558
367 + 137191 = 137558
439 + 137119 = 137558
571 + 136987 = 137558
607 + 136951 = 137558

Showing the first eight; more decompositions exist.
