Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137618, here are decompositions:

31 + 137587 = 137618
127 + 137491 = 137618
181 + 137437 = 137618
277 + 137341 = 137618
367 + 137251 = 137618
379 + 137239 = 137618
409 + 137209 = 137618
421 + 137197 = 137618

Showing the first eight; more decompositions exist.
