Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137886, here are decompositions:

13 + 137873 = 137886
17 + 137869 = 137886
19 + 137867 = 137886
37 + 137849 = 137886
59 + 137827 = 137886
83 + 137803 = 137886
109 + 137777 = 137886
149 + 137737 = 137886

Showing the first eight; more decompositions exist.
