Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137916, here are decompositions:

5 + 137911 = 137916
7 + 137909 = 137916
43 + 137873 = 137916
47 + 137869 = 137916
67 + 137849 = 137916
89 + 137827 = 137916
113 + 137803 = 137916
139 + 137777 = 137916

Showing the first eight; more decompositions exist.
