Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137960, here are decompositions:

3 + 137957 = 137960
13 + 137947 = 137960
19 + 137941 = 137960
157 + 137803 = 137960
223 + 137737 = 137960
307 + 137653 = 137960
337 + 137623 = 137960
367 + 137593 = 137960

Showing the first eight; more decompositions exist.
