Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137660, here are decompositions:

7 + 137653 = 137660
37 + 137623 = 137660
67 + 137593 = 137660
73 + 137587 = 137660
223 + 137437 = 137660
277 + 137383 = 137660
307 + 137353 = 137660
409 + 137251 = 137660

Showing the first eight; more decompositions exist.
