Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137874, here are decompositions:

5 + 137869 = 137874
7 + 137867 = 137874
43 + 137831 = 137874
47 + 137827 = 137874
71 + 137803 = 137874
83 + 137791 = 137874
97 + 137777 = 137874
103 + 137771 = 137874

Showing the first eight; more decompositions exist.
