Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137918, here are decompositions:

7 + 137911 = 137918
127 + 137791 = 137918
181 + 137737 = 137918
211 + 137707 = 137918
331 + 137587 = 137918
577 + 137341 = 137918
709 + 137209 = 137918
727 + 137191 = 137918

Showing the first eight; more decompositions exist.
