Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137958, here are decompositions:

11 + 137947 = 137958
17 + 137941 = 137958
31 + 137927 = 137958
47 + 137911 = 137958
89 + 137869 = 137958
109 + 137849 = 137958
127 + 137831 = 137958
131 + 137827 = 137958

Showing the first eight; more decompositions exist.
